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

    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...
