  • Sintered Tabular Alumina - China

    price: contact company for price

    1.Description Sintered tabular alumina is a kind of pure sintered

    corundum, which is sintered and completely shrink without adding any

    additive, such as MgO or B2O3, with coarse crystals and well-developed

    alpha Al2O3 crystal structure. The tabular crystal structure is

    characterized by narrow pores, with more closed porosity, almost the

    same apparent porosity compare with fused corundum , high purity, good

    stability volume density , tiny refiring shrink. After high

    temperature treatment, tabular alumina is used for refractory and

    castable characterized by good thermal shock stability and flexural

    strength. but the price is higher than the other alumina.

    2. Performance

    Tabular alumina is characterized by good heating volume temperature performance and good thermal shock resistance.

    3.Usage

    Tabular alumina is the perfect refractory raw material, which is widely used as the aggregate for producing various alumina refractory, it also can be used in other monolithic refractory. It can replace fused alumina and white fused alumina in some application position, and improve the performance of refractory material.
