Feature:
It has few impurity, and sintered at high or super high temp. State, and glass phase concentrates in the triangle zone of the crystalline phase, which are directly bonded to each other. It has low porosity, high compress strength, strong wearing and erosion resistance, excellent thermal shock stability and anti-spalling etc.
