CHROMIA-BASED BRICK
To provide a chromia-based brick having excellent corrosion resistance and thermal spalling resistance. Specifically, to provide a chromia-based brick which is suitable for use in sites which requirecorrosion resistance in a waste melting furnace, iron making equipment, an organic gasifier, or a glass melting furnace. [Solution] A brick containing chromia according to the present invention comprises: 70-95 mass% of Cr2O3; 0.5-15 mass% of ZrO2; 0.4-4.0 mass% of P2O5 derived from phosphoric acid which is compounded as a raw material; no more than 10 mass% of Al2O3; a sintering aid; and unavoidable impurities.
[课题]提供：耐腐蚀性和耐热散裂性优异的氧化铬质砖。提供：特别是可以适合用于废弃物熔融炉、炼铁用设备、有机物的气化炉和玻璃熔化炉的要求耐腐蚀性的部位的氧化铬质砖。[解决方案]本发明的含氧化铬的砖包含：Cr2O370～95质量％、ZrO20.5～15质量％、源自作为原料配混的磷酸盐的P2O50.4～4.0质量％、10质量％以下的Al2O3、以及烧结助剂成分和不可避免的成分。
