Die Erfindung bezieht sich auf ein Verfahren zum Herstellen eines temperaturwechselbeständigen, säurefesten keramischen Materials mit niedrigem Ausdehnungskoeffizienten, dichtem Scherben und hoher mechanischer Festigkeit auf der Basis von Berylliumverbindungen. The invention relates to a method for producing a temperature change-resistant, acid-resistant ceramic material with low coefficient of expansion, dense body and high mechanical strength based on beryllium compounds.
Die Erfindung knüpft an folgenden Stand der Technik an: Die hohe Säurebeständigkeit der Minerals Beryll 3 BeO · AL2O3 · 6 SiO2 ist allgemein bekannt. Es ist ferner bekannt, daß Beryll eine sehr niedrige Wärmeausdehnung (20 bis 20O0C) von etwa 1,5 bis 2,0 · 10~6 aufweist.The invention is based on the following prior art: The high acid resistance of the mineral beryl 3 BeO · AL 2 O 3 · 6 SiO 2 is generally known. It is also known that beryllium has a very low thermal expansion (20 to 20O 0 C) of about 1.5 to 2.0 x 10 ~. 6
Es sind weiterhin Sinterprodukte auf der Basis MgO-BeO—AI2O3 mit sehr geringem Glasgehalt bekannt, die gelegentlich als »temperaturbeständiges Porzellan« Verwendung finden. Diese Sinterprodukte enthalten aber kein Beryll, da die Kieselsäure fehlt. Außerdem ist noch eine hohe Wärmeausdehnung vorhanden. There are also known sintered products based on MgO — BeO — Al 2 O 3 with a very low glass content, which are occasionally used as "temperature-resistant porcelain". However, these sintered products do not contain any beryl because there is no silica. There is also a high degree of thermal expansion.
Ebenso ist es bekannt, Porzellan mit hoher Wärmeausdehnung vorzugsweise für Zündkerzen mit einem als vorteilhaft empfohlenen BeO-Bestandteil von 30 bis 40% herzustellen. Dieser hohe BeO-Gehalt ist aber nachteilig. Die bekannte Masse kann auch beim Brand keinen Beryll entwickeln.It is also known, porcelain with high thermal expansion preferably for spark plugs with a to produce the recommended BeO component of 30 to 40%. This high BeO content is but disadvantageous. The known mass cannot develop any beryl even in the event of a fire.
Ferner ist es bekanntgeworden, Beryll in Mengen bis zu 16°/0 als Flußmittel in Massen zu verwenden, die in überwiegendem Maße Talk enthalten. Die zu dichten Cordieritkörpern gebrannten Massen dieser Art werden in der Hochfrequenztechnik eingesetzt. Beryll wird bei diesen Massen ausschließlich als Flußmittel verwendet, so daß in dem gebrannten Scherben Beryll als solcher nicht mehr enthalten ist.Furthermore, it has become known, beryl in amounts up to 16 ° / 0 as a flux in masses to use mentioned in predominant extent Talk. The masses of this type fired to form dense cordierite bodies are used in high-frequency technology. Beryl is used exclusively as a flux in these masses, so that beryl as such is no longer contained in the fired cullet.
Es ist auch bereits versucht worden, in keramischen Massen auf MgO—AI2O3—SiO?-Basis, die noch Alkalimineralien, z. B. Feldspat, als Flußmittel enthalten, das Magnesiumoxyd durch Berylliumoxyd zu ersetzen. Die dabei angegebenen MgO-Gehalte liegen jedoch so hoch (bis 30 %X daß infolge von Enstatitbildung keine niedrige Wärmeausdehnung zu erzielen ist. Dasselbe gilt für den Fall, daß das Magnesiumoxyd durch Berylliumoxyd ersetzt wird.Attempts have already been made to use MgO — Al 2 O 3 —SiO ? -Base, which still contain alkali minerals, e.g. B. Feldspar, contained as a flux to replace the magnesium oxide with beryllium oxide. However, the MgO contents given are so high (up to 30% X that no low thermal expansion can be achieved due to the formation of enstatite. The same applies in the event that the magnesium oxide is replaced by beryllium oxide.
Ein anderes bekanntes Verfahren beschäftigt sich mit der Herstellung von keramischen Gegenständen durch Formen und Brennen von Gemischen aus tonigen Stoffen und Berylliumverbindungen. Als Formmasse sollen quarz- und feldspatfreie Gemenge aus Ton, Kaolin od. dgl. und Berylliumsilikaten verwendet werden. Hier erfordert die Abwesenheit von Alkalien den Zusatz eines Flußmittels. Als solche werden Erdalkaliverbindungen sowie Schwermetalloxyde vorgeschlagen.Another known method is concerned with the manufacture of ceramic objects by molding and firing mixtures of clayey substances and beryllium compounds. as Molding compounds should contain quartz- and feldspar-free mixtures of clay, kaolin or the like and beryllium silicates will. Here, the absence of alkalis requires the addition of a flux. As such Alkaline earth compounds and heavy metal oxides are proposed.

ao Schließlich ist noch ein elektrischer Isolierkörper bekanntgeworden, der in der Hauptsache aus den
Silikaten des Berylliums besteht. Dieser Isolierkörper soll gegebenenfalls neben Berylliumsilikat noch freies
Berylliumoxyd enthalten. Alle diese Bestandteile haben eine sehr hohe Wärmeausdehnung. Im übrigen
soll auf diese Weise in erster Linie eine gute elektrische Isolation und geringe dielektrische Verluste angestrebt
werden.
Der Erfindung liegt die Aufgabe zugrunde, keramisches Material mit hoher Temperaturwechselbeständigkeit,
guter Säurebeständigkeit und dichtem Scherben hoher Festigkeit herzustellen. Diese Aufgabe
wird erfindungsgemäß dadurch gelöst, daß das keramische Material aus einer Masse hergestellt wird, die
aus bis zu 90 Gewichtsprozent Beryll, mindestens 8 Gewichtsprozent frühsinterndem Ton und bis zu
2 Gewichtsprozent MgO oder entsprechenden Mengen Magnesiumverbindungen besteht, unter Zusatz von
Wasser zu Körpern geformt, dann getrocknet und bei einer Temperatur zwischen 1200 und 13500C gebrannt
wird.ao Finally, an electrical insulating body has become known, which mainly consists of the silicates of beryllium. This insulating body should also contain free beryllium oxide in addition to beryllium silicate. All of these components have a very high thermal expansion. In addition, good electrical insulation and low dielectric losses are primarily intended in this way.
The invention is based on the object of producing ceramic material with high thermal shock resistance, good acid resistance and dense body of high strength. This object is achieved according to the invention in that the ceramic material is produced from a mass which consists of up to 90 percent by weight beryl, at least 8 percent by weight early sintering clay and up to 2 percent by weight MgO or corresponding amounts of magnesium compounds, formed into bodies with the addition of water, then dried and fired at a temperature between 1200 and 1350 ° C.
Im Sinne der Erfindung liegt es, den Beryll ganz oder teilweise durch synthetischen Beryll zu ersetzen,
der beim Brennen einer Mischung von BeO, Quarz und Ton in einem dem Beryll entsprechenden Verhältnis
unter Zusatz von 0,5 bis 3 Gewichtsprozent MgO gebildet wird. Hierbei soll der Gehalt an BeO
und MgO nicht höher als 14 Gewichtsprozent sein.
Ferner ist gemäß der Erfindung vorgesehen, dem Rohversatz zusätzlich ein lithiumhaltiges Material in
einer weniger als 1% Lithiumoxyd entsprechenden Menge zuzusetzen.It is within the meaning of the invention to completely or partially replace the beryl with synthetic beryl, which is formed when a mixture of BeO, quartz and clay is fired in a ratio corresponding to the beryl with the addition of 0.5 to 3 percent by weight of MgO. The content of BeO and MgO should not be higher than 14 percent by weight.
Furthermore, it is provided according to the invention to additionally add a lithium-containing material in an amount corresponding to less than 1% lithium oxide to the raw batch.
