Abstract (en)
[origin: EP2168935A1] The material composition comprises a fine-grain fraction with grain size of less than 100 mu m and a coarse-grain fraction with grain sizes of more than 100 mu m. The fine-grain fraction comprises 90% of aluminum oxide having a grain size of 50-100 mu m, 5 wt.% of zirconium oxide having a grain size of 50-20 mu m, and 5 wt.% of stabilizer having a grain size of 50-20 mu m for the zirconium oxide and/or titanium oxide powder, in relation to the total weight of the fine-grain fraction. The coarse-grain fraction represents a weight fraction of more than 30 wt.% of the material composition. The material composition comprises a fine-grain fraction with grain size of less than 100 mu m and a coarse-grain fraction with grain sizes of more than 100 mu m. The fine-grain fraction comprises 90% of aluminum oxide having a grain size of 50-100 mu m, 5 wt.% of zirconium oxide having a grain size of 50-20 mu m, and 5 wt.% of stabilizer having a grain size of 50-20 mu m for the zirconium oxide and/or titanium oxide powder, in relation to the total weight of the fine-grain fraction. The coarse-grain fraction represents a weight fraction of more than 30 wt.% of the material composition and comprises an aluminum oxide-based crushed granulate and/or aluminum oxide-based hollow sphere structures. The zirconium oxide is partially or completely stabilized with the stabilizer and is monoclinic zirconium oxide. The stabilizer exists as an independent component of the fine grain fraction. The composition consists of 60-80 % of coarse-grain fraction. Hardened or sintered crushed granulate based on fine-grain fraction exists as crushed granulates. The crushed granulate is sintered at above 1300[deg] C. The composition consists of a dispersion medium and/or a plasticizer. Independent claims are included for: (1) a method for the production of a fireproof material; and (2) a fireproof material.
