    Analysis of anti-spalling mechanism of anti-stripping high alumina bricks

    The use of high alumina bauxite as the main raw material, the introduction of a small amount of ZrO2 (because ZrO2 is monoclinic and tetragonal phase transformation, can improve the products thermal shock stability), adding a certain amount...

    The nature of the mullite brick 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 is called mullite firebrick and the latter is called corundum-mull...

  • Classification of insulation materials

    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...
