Classification of insulation materials
The thermal conductivity of the insulating material is less than 0.23 W/(mC), and its porosity is generally above 70%. Due to the large amount of gas enthalpy L, the bulk density is small (usually below 0.5 g/c rr13) and the mechanical stre...

The nature of mullite refractory bricks determines its role
The firebrick made of sintered or fused mullite as the main raw material may be entirely made of mullite, partly may be mullite, and some may be made of corundum. The former became mullite refractory bricks, and the latter was called corund...
