Description

Verfahren zur Herstellung von gebrannten Quarzkunststeinen und feuerfesten Massen Es ist bekannt, daß man einen silikaähnlichen Quarzkunststein hoher Druckfestigkeit aus feingemahlenem, möglichst reinem Quarzsand unter gemeinsamem Zusatz von Fez O" und Alkalilauge bei einer Brenntemperatur von iooo bis 140d° herstellen kann.Process for the production of fused quartz artificial stones and refractories Compositions It is known that a silica-like quartz artificial stone of high compressive strength can be used from finely ground, as pure as possible quartz sand with the joint addition of fez O "and alkali can produce at a firing temperature of 100 to 140d °.

Die Neuheit der Erfindung besteht darin, daß es gelungen ist, einen hochwertigen Quarzkunststein und eine feuerfeste Masse dadurch zu erzielen, daß statt der Alkalilauge Fluorverbindungen, z. B. der Alkalien und Erdalkalien, verwendet werden.The novelty of the invention is that it has been possible to produce a to achieve high-quality artificial quartz stone and a refractory mass in that instead of the alkali fluorine compounds, e.g. B. the alkalis and alkaline earths used will.

Die Quarzkunststeine werden gepreßt und gebrannt, die feuerfesten Massen werden in Industrie- und Schmelzöfen in bekannter Weise eingestampft und durch Beheizen des Ofens oder auch durch eine indirekte Beheizung zum Sintern gebracht.The artificial quartz stones are pressed and fired, the refractory ones Masses are pulped in industrial and melting furnaces in a known manner and brought to sintering by heating the furnace or by indirect heating.
