PURPOSE:To obtain SiC refractory having excellent mechanical strength and improved thermal shock resistance. CONSTITUTION:This refractory comprises >=60wt.% SiC aggregate particles. The SiC refractory has 80-90wt.% theoretical density ratio and its grain boundary part consists of SiO2. The total amount of cristobalite existing as a subsidiary phase in the grain boundary part is 0.1-15.0wt.% based on the whole refractory. |
