Abstract：In order to meet the requirements of high cold compression strength and high thermal shock resistance, it discusses the effect of the different sintering process and andalusite powder particle size on the performance of products by using synthetic mullite and andalusite as the main raw material, supplemented by white corundum, suzhou clay,а-Al2O3. The results showed that superfine powder have an influence on close packing of product, added quantity with ≯ 10% is advisable, appropriate introduction of andalusite superfine powder can decrease the sintering temperature, and meet the product high strength and high heat stability of the procuct. The experiments prove that the firing process is a℃×8 h advisable, under the condition of introducing andalusite superfine powder.
