Description
Lithium-Porzellan Die Erfindung bezieht sich auf porzellanähnliche Körper mit sehr niedrigem Ausdehnungskoeffizienten, hoher Temperaturwechselbeständigkeit und porzellanähnlichen mechanischen Eigenschaften auf Li-Al-Silikatbasis ; sie besteht darin, daß Verbindungen des Bleis, Bors, Mangans, Kobalts und Lithiums einzeln oder in Mischung in Mengen bis zu 4% und/oder Tonmineralien und/oder Quarz in Mengen bis zu 30% zugesetzt werden.Lithium porcelain The invention relates to porcelain-like Body with a very low coefficient of expansion, high resistance to temperature changes and porcelain-like mechanical properties based on Li-Al-silicate; she consists that compounds of lead, boron, manganese, cobalt and lithium individually or in a mixture in amounts up to 4% and / or clay minerals and / or quartz in amounts up to 30% can be added.
Die Verwendung von Lithium-Massen zur Herstellung keramischer Körper ist bekannt. Es werden hierfür besonders Lithium-Aluminium-Silikate wie Spodumen und Eucryptit und deren Zwischenprodukte verwendet. Es ist bekannt, daß damit Körper mit einem Ausdehnungskoeffizienten von -3 - 10-B bis 3 - 10-B erhalten werden können. Dies ist darauf zurückzuführen, daß diese Lithium-Silikate Kristallformen aufweisen, welche den Hochtemperaturmodifikationen der Kieselsäure ähneln. Derartige Körper haben aber den großen Nachteil, daß sie porös sind und außerdem sehr schwierig zu brennen sind, da sie eine sehr enge Sinterperiode besitzen. Sie sind deshalb für industrielle Erzeugung kaum geeignet.The use of lithium masses for the production of ceramic bodies is known. Lithium aluminum silicates such as spodumene are particularly used for this purpose and eucryptite and their intermediates are used. It is known that with it body with an expansion coefficient of -3-10-B to 3-10-B can be obtained. This is due to the fact that these lithium silicates have crystal forms, which resemble the high temperature modifications of silica. Such bodies but have the major disadvantage that they are porous and also very difficult to are burning because they have a very narrow sintering period. They are therefore for industrial production hardly suitable.
Auch hat man schon vorgeschlagen, glasige Körper herzustellen der allgemeinen Zusammensetzung 33 Teile Borsäure, 33 Teile Mennige, dazu 9 Teile Lithiumnitrat bzw. 15 Teile Lithiumcarbonat. Ferner kann auch ein Lithiummineral »Lepidolith« verwendet werden, das bis zu 60°/o höchstens zum Einsatz kommt; die restlichen 40°/o bestehen aus Borsäure und Blei-Mennige. Derartige Glasflüsse werden beispielsweise zum Einbrennen von Aufglasurfarben verwendet; porzellanartige Körper lassen sich daraus aber nicht formen. Zur Herstellung von Zündkerzen, Isolatoren und ähnlichen Geräten hat man auch bereits Massen verwendet, die aus mindestens 92% A120, bestehen und bei wenigstens 1650° gebrannt werden.It has also already been proposed to produce glassy bodies with the general composition 33 parts boric acid, 33 parts red lead, plus 9 parts lithium nitrate or 15 parts lithium carbonate. Furthermore, a lithium mineral "lepidolite" can be used, which is used up to 60% at most; the remaining 40 per cent. consist of boric acid and red lead. Such glass flows are used, for example, for baking on-glaze colors; However, porcelain-like bodies cannot be formed from it. For the production of spark plugs, insulators and similar devices, compounds have already been used which consist of at least 92% A120 and are burned at at least 1650 °.
Demgegenüber handelt es sich bei der Erfindung um porzellanartige Massen, die nachstehende Eigenschaften aufweisen: Sie besitzen a) einen Ausdehnungskoeffizient in der Größenordnung von -3 bis -I- 10 - 10-7, b) eine außerordentlich hohe Temperaturwechselbeständigkeit, c) eine Wasseraufnahme von 0 bis etwa 0,5%; d) sie sind in ihren mechanischen Eigenschaften ähnlich normalem Porzellan und sind e) nach normalem keramischem Verarbeitungsverfahren (Drehen, Gießen usw.) zu verarbeiten. Dies wird technisch dadurch ermöglicht, daß den Lithium-Aluminium-Silikaten Zusätze zugefügt werden, welche bewirken, 2 1. daß die einzelnen Lithium-Aluminium-Silikatkristalle fest aneinandergekittet werden, 2. die eine solche Zwischenschicht bilden, welche die günstigen Eigenschaften der Lithium-Aluminium-Silikate nicht oder nur wenig beeinflußt, 3. welche mit dem verwendeten Lithium-Aluminium-Silikat ganz oder zum Teil ein neues Lithium-Aluminium-Silikat bilden, das die gewünschten Eigenschaften aufweist.In contrast, the invention is porcelain-like Compounds that have the following properties: They have a) a coefficient of expansion in the range of -3 to -I- 10 - 10-7, b) an extraordinarily high thermal shock resistance, c) a water uptake of 0 to about 0.5%; d) they are in their mechanical properties similar to normal porcelain and are e) after normal ceramic processing methods (Turning, casting, etc.). This is technically possible in that the lithium-aluminum-silicates additives are added which cause 2 1. that the individual lithium aluminum silicate crystals are firmly cemented together, 2. which form such an intermediate layer, which the favorable properties of the Lithium-aluminum-silicates not or only slightly influenced, 3. which with the used Lithium aluminum silicate in whole or in part a new lithium aluminum silicate form that has the desired properties.
Als derartige Zusätze eignen sich unter anderem Boroxyd, die Chloride des Mangans und des Kobalts und Lithiummolybdate. Außerdem können den ursprünglichen Lithium-Aluminium-Silikatfritten Tonmineralien in solcher Menge zugefügt werden, daß im Brand neue Lithium-Aluminium-Silikate mit den gewünschten Eigenschaften entstehen.Such additives include boron oxide, the chlorides of manganese and cobalt and lithium molybdates. You can also use the original Lithium aluminum silicate frits are added to clay minerals in such an amount that that new lithium aluminum silicates with the desired properties are created in the fire.
Als Beispiele für derartige Versätze seien folgende genannt: 1. Man frittet 1 Mol Lithiumcarbonat, 1 Mol Aluminiumoxyd und 6 Mol Si 02 mit einem Zusatz von 511@ Zirkonoxyd bei Temperaturen von 1100 bis 1300°, zerkleinert diese Fritte, mahlt sie und gibt auf 100 Teile dieser Fritte 1 Gewichtsteil Manganchlorid, 6 Gewichtsteile Boroxyd und 15 Gewichtsteile feuerfesten Ton. Diese Menge wird bei etwa 1300 ,bis 1350° gargebrannt.The following are examples of such offsets: 1. Man frits 1 mol of lithium carbonate, 1 mol of aluminum oxide and 6 mol of Si 02 with an additive of 511 @ zirconium oxide at temperatures from 1100 to 1300 °, this frit comminutes, grinds it and gives 1 part by weight of manganese chloride, 6 parts by weight, to 100 parts of this frit Boron oxide and 15 parts by weight of refractory clay. This amount is around 1300, up Cooked at 1350 °.
2. Man frittet 1 Mol Lithiumcarbonat, 1 Mol Aluminiumoxyd und 4 Mol Si 02 mit 5%: Zirkonoxyd und gibt 100 Teilen dieser Fritte 5 Teile einer weiteren Fritte aus 50 Teilen Si 02 und 50 Teilen B2 03 zu sowie außerdem 2 Teile Manganchlorid. Diese Masse wird bei 1300 bis 1330° gebrannt.2. One frits 1 mol of lithium carbonate, 1 mol of aluminum oxide and 4 mol Si 02 with 5%: zirconium oxide and gives 100 parts of this frit 5 parts of another Frit made from 50 parts of Si 02 and 50 parts of B2 03 and also 2 parts of manganese chloride. This mass is burned at 1300 to 1330 °.
3. 100 Teile der unter Nummer 1 genannten Fritte werden mit 3 Teilen Lithium-Molybdat, 2 Teilen Bleifluorid, 1 Teil Boroxyd und 15 Teilen Kaolin versetzt und bei 1300 bis 1320° gargebrannt.3. 100 parts of the frit mentioned under number 1 are made with 3 parts Lithium molybdate, 2 parts lead fluoride, 1 part boron oxide and 15 parts Kaolin is added and burned at 1300 to 1320 °.
4. 100 Teile der unter Nummer 2 genannten Lithiumfritte werden 20 Teile Kaolin und 14 Teile Quarz zugesetzt.4. 100 parts of the lithium frit mentioned under number 2 are 20 Parts of kaolin and 14 parts of quartz were added.
