Description
Verfahren zur Herstellung höchst feuerbeständiger und anderer keramischer Erzeugnisse Man weiß, daß Zirkonerde, das Oxyd des Zirkoniums, einen vorzüglichen Rohstoff für die Keramik bildet. Aber das zur Herstellung dieses Stoffes dienende mineralische Zirkonsilikat hat eine sehr veränderliche Zusammensetzung und findet sich in Mischungen mit Fremdkörpern im Verhältnis von ungefähr 15 :25 Prozent, wie die Oxyde des Eisems. des Mangans, des Titans, wie Tonerde, Kieselsäure usw. Diese Fremdkörper ändern die Eigenschaften des Zirkonoxvdes, und wenn inan gute keramische Stoffe mit dem Zirkonmineral erhalten will, sind lästige chemische Reinigungen notwendig, deren Kosten der gewerblichen Entwicklung von keramischen Erzeugnissen auf Grundlage des Zirkonoxydes im \N'ege standen.Process for the manufacture of highly refractory and other ceramic Products It is known that zirconia, the oxide of zirconium, is an excellent one Raw material for the ceramic forms. But the one used to manufacture this substance mineral zirconium silicate has a very changeable composition and takes place in mixtures with foreign bodies in a ratio of approximately 15:25 percent, such as the oxides of iron. of manganese, titanium, such as alumina, silica, etc. These Foreign bodies change the properties of the zirconium oxide, and if inan good ceramic If you want to preserve substances with the zirconium mineral, annoying chemical cleaning is necessary, whose cost is based on the commercial development of ceramic products of the zirconium oxide were in the \ N'ege.
Man hat schon auf die Verwendung von Zirkonmineralien hingewiesen, die einen großen Gehalt ZrO" der bis zu 97 Prozent geht, enthalten und in Brasilien vorkommen. Diese Mineralien von 9:4 bis 97 Prozent, die .unter dein Namen Favas bekannt sind, sind ;ehr selten. Man hat ebenso schon mit gewissen Mineralien -ersuche gemacht, welche im Gegensatz zu den meisten Zirkonminrralien aus regelmäßig konstituiertem Zirkoniunisilikat l;estehen und der Forniel "/.rO.,Si()_ eutslircchen. Dabei handelt es sich aber um brasilianisclie Mineralien, die immer :iiiiorlili und unrein sind und neben anderen \'crbindung:#ii Eisenoxv d in verschiedenen Verhältnissen bis zu 9 Prozent enthalten, und die auch eines vorherigen lästigen und verwickelten Reinigung unterworfen werden müßten.The use of zirconium minerals has already been pointed out, which contain a large ZrO "content that goes up to 97 percent and in Brazil occurrence. These minerals from 9: 4 to 97 percent that .under your name Favas are known are; rather rare. You also have to search for minerals with certain minerals which, in contrast to most zirconium minerals, consist of regularly constituted Zirconium silicate and the form "/.rO.,Si()_ eutslircchen But they are Brazilian minerals, which are always: iiiiorlili and impure and among other bonds: #ii Eisenoxv d in various ratios up to 9 percent included, and those of the previous bothersome and involved Would have to be subjected to cleaning.
Der Zweck der. vorliegenden Erfindung iss die Herstellung von ultrafeuerbeständigen keramischen Massen und Schleifmitteln auf des Grundlage des eigentlichen natürlichen oder künstlichen Zirkons, welches aus vollständig oder annähernd reinem Zirkonsilikat besteht und der läcirniel SiO,Zr entspricht. Das natürliche Vorkommen dieses Zirkonsilikats hat eine gast ausgebildete und oft umfangreiche Kristallform und ist von Fremdkörpern fast frei. Diese Kristalle kommen im allgemeinen von der Insel Madagaskar. Der Zirkon ist ein liiirlier, welcher ohne Aufblähung, Sinterung oder Schmelzung einerTemperatur von 2ooo° widersteht, geiuesser mittels Gier französischen Dezimalprobescherben. Er dehnt sich nicht aus und schwindet nicht, nachdem er einer hohen Temperatur unterworfen worden ist, und ist unempfindlich gegen plötzliche Temperaturänderungen und widerstandsfähig gegen Alkalien und Säuren und außerdem ein Schleifniittel. Uni aus dieseln Ausgangsstoff keramische Massen herzustellen, wird er gemahlen, iiacli(lrni er vorzugsweise vorher kalziniert t)rler gebrannt- worden ist.The purpose of. The present invention is the manufacture of ultra fire resistant ceramic masses and abrasives based on the actual natural or artificial zircon, which is made from completely or nearly pure zirconium silicate and the läcirniel SiO, Zr corresponds. The natural occurrence of this zirconium silicate has a hospitable and often extensive crystal form and is made up of foreign bodies almost free. These crystals generally come from the island of Madagascar. The zircon is a liiirlier, which without swelling, sintering or melting of a temperature Resists of 2ooo °, geiuesser by means of greed French decimal test. It does not expand or shrink after being subjected to a high temperature and is insensitive to sudden changes in temperature and resistant against alkalis and acids and also an abrasive. Uni made of diesel raw material To produce ceramic masses, it is ground, iiacli (lrni er preferably beforehand calcined t) rler has been burned.
Wenn die \lahlung in einer 1?isen oder Stahl aufweisenden \-orriclitung erfolgt, löst der Zirkon als Schleifmittel -Metallteilchen ab, ilie man in gewissen 1#'ällen durch magnetische Scheidung- wieder entfernen inuß. Maiensn kann man zur Entfernung des aus der Mahlung stammenden Metallgehaltes verdünnte Mineralsäuren verwenden. Nach der Mahlung wir' das Zirkonsilikat ohne irgendeine clienii#clic Reinigung mit einem Bindemittel versehen, welches entweder organischer Natur nein kann, wie Dextrin, Gummi, Lein tisw., uni dessen Beimischung dann eine starke Pressung folgt, oder man kann basisch neutrale oder saure lIineralien verwenden, deren Auswahl und -Menge sich nach der Art der erwünschtenkeratnischen -Masse ändert. Diese agglomerierten -Massen werden dann auf eine hohe Temperatur bebracht, je nachdem zwischen i.loo=bis t;oo° C. Beispiel i. Die -Mischung wird zusammengesetzt aus 3 'feilen gelclschtein Kalk und 0; Teilen rlerart geniahlenein Zirkonsilikat. datl e. in Korn- tinrl Pulverfnrin vc)rlic;:t und bei eitler Temperatur von niin,lezte;i: i.tc,ri (' Zchranut.

Maiensn can use dilute mineral acids to remove the metal content from grinding. After grinding, the zirconium silicate is provided with a binding agent without any clienii # clic cleaning, which can either be of an organic nature, such as dextrin, gum, flax, etc., whose admixture is then followed by strong pressing, or it can be alkaline-neutral or acidic Use minerals, the selection and quantity of which changes according to the type of ceramic compound desired. These agglomerated masses are then brought to a high temperature, depending on between i.loo = to t; oo ° C. Example i. The mixture is composed of 3 'files slaked in lime and 0; Share a zirconium silicate. datl e. in Korn- tinrl powderfnrin vc) rlic;: t and at a vain temperature of niin, last; i: i.tc, ri ('Zchranut.
