Definitions
- the present invention relates to the use of soluble rare earth compounds in combination with other coloring transition metal compounds of ceramic bodies.
- Metal oxides are generally used for coloring ceramic materials and are stable at the usual firing temperatures of 700 to 1400 ° C.
- the colored oxides of iron are used in particular.
- Chrome Manganese, pure and mixed phases with spinel structure, for example compounds of Al. Ni. Cr. Zn. Co. Cu, Mn. Fe. U and V. a series of silicates. Sulfides and mixed phases with working cations in colorless host lattices of the rutile type such as Ti0 2 . SnO 2 . Zr0 2 . ZrSiO 4 and PbO 2 .
- the rare earth metals are elements of the 3rd group of the Periodic Table, they belong to the transition metals.
- the rare earth elements include the elements scandium. Yttriumv and the 14 elements following lanthanum, from lanthanum to lutetium, which are essentially 3+ valued, occur naturally in the form of oxides. At this stage of oxidation they have a wide variety of colors.
- the compound is Neodym3 + red-violet or Praseodym3 + green-yellow.
- rare earth oxides for this. These oxides are usually water-insoluble and are applied as pigments to the ceramic body by different methods.
- the use of the rare earth oxides as coloring pigments for ceramics is known from DE 19739124. The use of these oxides to produce purple ceramic decorations is described here.
- the pigments are based on a burnable carrier material. for example a glass flow, a rare earth oxide hydrate and a gold compound or colloidal gold. In this special process the oxide hydrates of the elements are yttrium. Lanthanum. Cerium and scandium used.
- WO 97/08115 describes a further process for the production of ceramic coatings and the coating powders suitable therefor.
- the coating powders can be rare earth oxides.
- the process described here is electrostatic coating with oxide powders of a certain size. using specially designed adhesives.
- the so-called fire-capable substrates are used as substrates, including, in particular, enamelable metals and ceramic materials. e.g. Glass. Fine ceramics (porcelain. Bone China and Vitreous China. Building ceramics (roof tiles. Tiles), as well as sanitary ceramics and decorative ceramics.
- the substrates can be coated with powders that are particularly easy to fluidize, ie, liquefy
- This good fluidization of the coating powder does not give rise to any technical problems during spraying, the surface of the substrate is smooth, not corrugated, and it is also possible to achieve a corresponding coating depth on the surface of 100 to 700 ⁇ m.
- DE-197 01 080 Cl describes a process for coloring ceramic surfaces, which is characterized in that. that a colorless oxide crystallizing in the spinel or rutile lattice is incorporated into a ceramic mass or a surface layer made of the ceramic mass as the host lattice.
- an aqueous coloring solution which is a soluble compound of a divalent or trivalent metal ion coloring the host lattice and contains a soluble compound of a pentavalent or hexavalent metal ion for electrostatic compensation, is produced in which.
- the ceramic body is fired at 300 to 1400 ° C and a burning time of 0.5 to 5 hours.
- the advantage of this method is that the coloring solutions can be applied to the surface quite uniformly (sprayed, dipped, etc.) and the color layers produced in this way have a depth of 0.5 to 2 mm. This depth allows it. to subsequently process the ceramic surface by grinding and polishing, but also to create certain surface patterns.
- the soluble salts of the transition metals are used as coloring solutions.
- the combination of antimony and chromium salts used here produces the color yellow;
- the colors pink or black can be produced in a similar manner, see DE-195 46 325 C1 and DE-196 25 236 Cl.
- the colors created here are usually quite intense; it is not possible to use matt or pastel shades with the methods described above. To create chandelier effects without the involvement of precious metals or even color gradations. Often, only a certain lightening or decolorization of the ceramic substrates is desired, which cannot be achieved with these coloring methods. It is also not possible to lighten the colored substrates by applying less concentrated coloring solutions because the low concentration means that the layer thickness of the colored surface layers generated is too small to allow subsequent processing.
- the ceramic substrate Applies ceramic substrate, and after drying the solvent, the ceramic substrate between 300 and 1400 ° C. and burns for 0.5 to 2.5 hours.
- Acetates are the water-soluble salts of rare earths. the citrate. Chlorides.
- Nitrates Oxalates and sulfates used.
- the coloring solutions for the production of pigments of the rutile type consist of a water-soluble compound of a divalent or trivalent metal ion, in particular from the group nickel. Cobalt and chromium, as well as another soluble compound of a pentavalent or hexavalent metal ion, especially antimony. Niobium or tungsten, the salts in a concentration of about 1 to 10% by weight. preferably 2 to 5% by weight. are included. Oryanic acids and in particular are preferred as anions complex-forming acids are used, which on the one hand have very good dissolving properties and on the other hand burn in an environmentally friendly manner with the formation of water and CO 2 . However, inorganic anions such as chloride or nitrate can also be used, provided that the disadvantages associated with this are accepted.
- the solution has proven to be advantageous for the solution to have complex titanium, in particular potassium titanium oxalate. to add, although the amounts are limited to less than 3% due to the low solubility of this compound.
- the mixed phase coloring is enhanced by this addition, possibly by promoting the growth of a mixed phase on the existing host lattice.
- titanium dihydroxy bis [2-hydroxypropanato (2 " ) - ⁇ '.0 2 ] titanate (2 " )
- ammonium salt CA Reg. No. 85104-06-5
- the Na and K compounds and compounds with other ammonium ions also have corresponding stabilities.
- these compounds can be mixed with salts of trivalent and pentavalent ions, as are customary for the mixed phase formation of rutile lattices, in concentrations which are sufficient for direct coloring of ceramic surfaces without the interaction of the different anions leading to incompatibility.
- Anions in these salts are organic acid residues, such as acetate. Tartrate. Citrate or lactate is preferred because they are oxidized to CO 2 when burned.
- Inorganic salts like chlorides. However, sulfates or nitrates can be also use. 1-3% by weight of the tri- and pentavalent ions and 3-8% by weight of the titanium are preferred.
- the staining solutions are sprayed. Diving. To paint. Printing etc. only applied to the parts of the surface that are to be colored, whereby the solutions penetrate more or less deeply into the ceramic mass, depending on the amount applied. Discoloration usually occurs to a depth of 0.5 to 2 mm. so that both a patterning of the surface and processing, for example by grinding or polishing, is possible.
- Titanium dioxide is preferably used as the host lattice for rutile pigments, but also SnO 2 . Zr0 2 and other oxides customary for this purpose can be used.
- MgAl 2 ⁇ 4 compounds are the host lattice for spinels.
- ZnAl 2 0 4 or Zn (TiZn) O 4 , Mg 2 TiO 4 , Zn 2 TiO 4 can be used.
- the organic ligands of the metal compound are burned by burning, or inorganic anions are evaporated, and the remaining metal oxides are incorporated into the silicate phase of the ceramic or, with the formation of colored pigments, into the specified host lattices.
- the mixed phase pigments formed according to the invention allow this. to expand the spectrum of subsequent coloring of ceramic surfaces extraordinarily and to apply a multitude of new shades in a targeted manner.
- the following experiments illustrate the subject of the invention in more detail using the example of the production of rutile pigments, without restricting it.
- the color shade obtained was determined using a Minolta Chroma Meter CR 200, using the CIE standard illuminant C (6774K).
- the L * a * b * color system recommended in ISO and DIN standards was used to determine the values.
- the L * a * b * color system represents a color body through which three axes have been laid.
- the vertical axis is the L * axis and represents the brightness of the color.
- the axes a * and b * are located in the horizontal plane (color wheel), where a * stands for the hue and b * for the saturation.
- a typical lemon yellow has, for example, the brightness L * 81, 5; an a * value around 0 and a high b * value of 62.5
- a general problem in the experiments mentioned above is the low titanium concentration in aqueous solution (2.9%). which prevents a deepening of the color tone in that no larger portion of the surface is covered with a TiO 2 grid.
- the so-called engobing technique offers a solution here. which consists in enriching the surface with TiO 2 .
- the engobe clay can either be naturally or artificially enriched with TiO 2 .
- the clay flour was processed as follows: The clay was ground in a ball mill and sieved through a sieve with a mesh size of 0.063 mm. The viscosity was regulated by using condensers (max. 0.1%) based on silicate or acrylate. The blanks were then engobed by pouring over and draining. After drying overnight, the moldings thus obtained were sprayed with the appropriate chromophore solution and then fired at 1,140.degree.
- TiO? brightens the color very clearly and changes its quality in the case of iron, where there is a shift from reddish brown to yellowish.
- Ceramic cullet with a TiO 2 content of ⁇ 0.1 wt .-% and otherwise the composition corresponding to experiment VI are sprayed with the following solutions, dried and fired at 1,140 ° C.
