Sintered corundum
Ultra high temperature sintered tabular corundum, alumina as raw material, after grinding forming and drying, rapid heating cooling conditions in ultra high temperature in the kiln, self growth become many closely in columnar crystal products. The grain size is generally 30-200um, and the interior contains many enclosed micro pores, which belong to the high alumina corundum with high purity.
Special production process of the product, it determines the unique properties: high refractoriness, high corrosion resistance, high abrasion resistance, high heat resistance and chemical properties of shock resistance, high strength and high toughness, stable, refractory, ceramic and electrical insulation is the ideal raw material, but also with abrasive grinding and polishing and grinding industry the ideal high-end materials.
According to the needs of users, customized production of 25mm-10um specifications of various kinds of tabular corundum particles and micro powder.
