1. Chemical composition: main ingredients decide quality and features of the refractory material.
2. Bulk density: per unit volume weight, big density, show good compactness, strength may be high, but the coefficient of thermal conductivity may be larger.
3. Thermal shock resistance: resistance to the ability of rapid changes in temperature and not damaged.
4. The compressive strength : bear ( normal temperature) the biggest pressure ability.
5. The flexural strength: bear the ability of shear pressure .
The physical and chemical properties:
1. Wear resistance
2. Thermal conductivity: under the condition of unit temperature gradient, through the material on heat flow rate per unit area, related to porosity.
3. Impact resistance: good impact resistance, long service life.
4. Slag resistance: at high temperature has the ability of resistance slag erosion without damage.
