High-temperature alumina powder uses industrial aluminum hydroxide or industrial alumina as raw materials, and is calcined at an appropriate temperature to form a stable crystalline α-type alumina product; it is made from calcined α-type alumina through ball milling Alumina powder.
High temperature alumina powder: white, shiny, high purity, stable chemical properties. Has good insulation. The microhardness is 2200-2300km/mm2. It can be used as fixed abrasive tools and coated abrasive tools, wet or dry jet powder, super-precision grinding and production of high-grade wear-resistant materials. It is suitable for processing hardened steel, alloy steel, high-speed steel, high-strength steel and other materials with strong hardness and high compressive strength. It is also suitable for grinding and polishing piezoelectric crystals, semiconductors, monocrystalline silicon, polycrystalline silicon, etc. It can also be used as catalyst parts, insulating parts, special ceramics and advanced refractory materials.
Uses: Widely used in high-aluminum refractory materials, high-aluminum refractory balls, corundum bricks, grinding and polishing, refractory bricks, alumina ceramics, etc.
Features: High-temperature alumina is specially produced for refractory material enterprises. It has the characteristics of high conversion rate, good fluidity, good dispersion, and uniform particle size. High-temperature alumina powder is especially suitable for refractory materials.
