Abstract

Die Erfindung betrifft einen thermoschock- und korrosionsbeständigen Keramikwerkstoff auf der Basis von Calciumzirkonat sowie ein Verfahren zur Herstellung des Werkstoffes. Aus dem Keramikwerkstoff können geformte oder ungeformte Erzeugnisse für die Energietechnik, die Metallurgie, die Automobilindustrie, die Glas- und Zementindustrie und die chemische Industrie hergestellt werden. Der Erfindung liegt die technische Aufgabe zugrunde, einen thermoschock- und korrosionsbeständigen Keramikwerkstoff zu entwickeln, aus dem großvolumige Voll- und Hohlbauteile herstellbar sind. Zur Gewährleistung einer hohen chemischen Beständigkeit soll die keramische Bindematrix in der Zusammensetzung der Werkstoffzusammensetzung weitgehend entsprechen. Erfindungsgemäß besteht das Gefüge des Werkstoffes aus vorsynthetisiertem calciumcirkonathaltigen Brechgranulat mit einem ZrO2/CaO-Verhältnis zwischen 1,6 : 1 und 1 : 1,5 und einer Korngröße von 150 μm bis 6 mm mit einem Anteil größer 50 Masse% und einer das Brechgranulat umgebenden bei > 1400 °C gesinterten Bindematrix aus feinkörnigem Calziumzirkonat und/oder Zirkonoxid mit Korngrößen zwischen 50 nm und 150 μm.
