发明名称 Fireclay brick used as a base for a tin bath comprises an aluminum-silica system material with fine and coarse regions
摘要 Fireclay brick is made of a material of the system Al2O3-SiO2 comprising a fine grain region of less than 0.075 mm with more than 65 wt.% SiO2and less than 35 wt.% Al2O3, which serves an enlarged alkali and silicic acid offer to form a glass phase in the fine grain region through a lowered Al2O3. The material has a coarse grain region of more than 1500 mm with less than 65 wt.% SiO2 and more than 35 wt.% Al2O3. An Independent claim is also included for the manufacture of the fireclay brick comprising molding a material of the system Al2O3-SiO2, drying, calcining and grinding.
