Abstract
A material composition for producing a fireproof material having a fine-grain fraction with grain sizes of less than 100 μm and a coarse-grain fraction with grain sizes of more than 100 μm is provided. The fine-grain fraction includes aluminum oxide having a weight proportion of at least 90% by wt. in relation to the total weight of the fine-grain fraction, zirconium oxide having a weight proportion of up to 5% by wt. in relation to the total weight of the fine-grain fraction, a stabilizer for the zirconium oxide as well as titanium oxide powder having a weight proportion of up to 5% by wt. in relation to the total weight of the fine-grain fractional. The coarse-grain fraction represents a weight fraction of more than 30% by wt. of the material composition.
