Alumina, a stable oxide of aluminium, is also known as bauxite in mining, ceramics and materials science.

USES: used as analytical reagent, dehydration agent, adsorbent, organic reaction catalyst, grinding agent, polishing agent, raw material of aluminum smelting, refractory.

Alumina is used to make brown corundum by electrically melting high quality bauxite ore, while high quality aluminate is used to make pink corundum and white corundum.Their natural crystal structure makes them hard and fast to cut.At the same time, they are often used as the raw materials for consolidating and coating abrasives.

Alumina can be recycled for many times, the number of cycles is related to the material grade and the specific process, most of the standard abrasive sandblasting equipment can be used.

Industry scope: aerospace industry, automobile industry, consumer goods processing, casting/die-casting, OEM distributor, semiconductor industry and other fields.

Scope of application: pretreatment before surface plating, painting, glazing and coating with ptfe;Aluminum and alloy products to deburr, to pot scale;Mold cleaning;Pretreatment before metal blasting;Dry and wet grinding;Precision optical refraction;The grinding of minerals, metals, glass and crystals;Glass carving and paint additive.

Alumina is divided into calcined alumina and ordinary industrial alumina. Calcined alumina is an essential raw material for the production of antique bricks, while industrial alumina can be used for the production of microspar. In traditional glazes, alumina is often used for whitening.Because archaize brick and microspar were favored by the market, the dosage of alumina is also increasing year by year.

Therefore, alumina ceramic in ceramic industry arises at the historic moment, alumina ceramic is a kind of Al ₂ O ₃ as the main raw material, ceramic material is given priority to with corundum crystal phase. Because of its high mechanical strength, high hardness, low dielectric loss at high frequency, high temperature and high insulation resistance, chemical corrosion resistance and good thermal conductivity and other excellent comprehensive technical performance advantages.
