1. High temperature strength;

2. Resistant to corrosion in various atmospheres;

3. Excellent thermal shock stability;

4. Good thermal insulation;

5. The energy-saving effect is remarkable
The operating temperature is below 1350C. Thermal insulation refractories are characterized by high porosity, generally 40%-85%; Low bulk density and low dry 1.5g/cm3: low thermal conductivity, generally less than 1.0W (m.K), it acts as the thermal insulation material of industrial kiln, can reduce the heat dissipation loss of the furnace, save energy, and can reduce the quality of the equipment under heat, the mechanical strength, wear resistance and slag erosion resistance of the thermal insulation refractory material is poor, and it is not suitable for the load-bearing structure of the kiln and direct contact with slag, charge, molten metal and other parts
