Product Description
high temperature resistance alumina Ceramic Bushing sleeve
Reputation depends on quality, quality comes from Hard!
Alumina is a white solid, also known as bauxite in mining, ceramics and materials science.Alumina is only second to silicon oxide in the earth. It is one of the ceramic raw materials, aluminum and oxygen in the oxide.Strong bonding, which gives alumina the highest hardness in oxides, high chemical stability and excellent corrosion resistance for most acidic, alkaline, salt and molten solutions.Alumina has many isomorphous crystals, and there are currently more than 10 kinds of crystals, mainly three crystal forms, namely α-Al2O3, β-Al2O3, and γ-Al2O3. Among them, the structure has different properties, and is almost completely converted into α-Al2O3 at a high temperature of 1300 ° C or higher.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.
High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
