Spherical alumina application description: Due to its high thermal conductivity, low oil absorption, good fluidity, insulation, and corrosion resistance, spherical alumina is a key filler and raw material in the fields of electronics, thermal conductivity, ceramics, and chemicals.
Corundum-grade alumina: A high-performance refractory material, it is a primary raw material for manufacturing refractory bricks, castables, and ceramic fibers, widely used in steelmaking furnaces, glass melting furnaces, cement kilns, and waste incineration plants. It effectively resists high-temperature erosion, extends the service life of industrial equipment, and reduces customer maintenance costs.
DA-Series Calcined α-Al₂O₃ Powder
The DA series Calcined α-Al₂O₃ micro powder is the result of the national "7-5" research project. In 1990, through national identification, the technology reached the international advanced level.
Our DA series calcined α-Al₂O₃ micropowder is produced by calcining industrial aluminum hydroxide or industrial alumina at appropriate temperatures to form crystallographically stable α-alumina products.
