Features:

1. High bulk density, high purity, high refractoriness under load;
2. Low thermal expansion, excellent thermal shock resistance;

3. Strong resistance to slag, low reheating contract and creeping rate;

4. Excellent chemical stability against alkali attack, good eroding resistance;

5. Strong slag-resistance, good wear-resistant, high mechanical strength under high temperature.

Application:

1. First choice for the lining of the glass melting tank and regenerator walls.

2. Widely used in the lining of thermal storage tank, ceramic frit kiln, and chemical furnace.

3. Widely used in ceramic frit furnace, sodium silicate furnace, glass furnace metallurgy, building material, electronic,

and other industry furnaces.
