Alumina Ceramic:

Alumina contains the elements aluminum and oxygen. If the bauxite raw material is chemically treated to remove oxides of silicon, iron, titanium, etc., the product obtained is a high purity alumina raw material, and the Al2O3 content is generally above 99%. The mineral phase consists of 40% to 76% γ-Al2O3 and 24% to 60% α-Al2O3. γ-Al2O3 can be converted to α-Al2O3 at 950-1200 °C, and significant volume shrinkage occurs at the same time. There are many variants of Al2O3, the common ones are α, and the γ forms are all white crystals.
The corundum in nature is the most densely packed α-shaped hexagon, with melting point, high hardness, insoluble in acid and alkali, corrosion resistance and good insulation.
The aluminum hydroxide and the aluminum hydroxide or aluminum ammonium lanthanum are co-heated at 723K to obtain a γ-shape, which is insoluble in water, but has strong water absorption, strong adsorption capacity and catalytic activity.
The beta shape has ion conductivity and allows Na+ to pass. The data shows that China is the world's largest alumina producer. In 2010, global alumina production was 565.35 million tons, and China's alumina output reached 28.95 million tons, up 20.14% year-on-year, accounting for 51.38% of the global total. In 2010, the apparent consumption of alumina in China reached 33.21 million tons, with an annual growth rate of 14.05%, a net import of 4.26 million tons, a bauxite import of 30.19 million tons, and an external dependence of 39.71%. Up to 27.26%.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
