Alumina ceramics are a common special ceramic with alumina as the main component. They have the advantages of high hardness, high strength, high heat resistance, high insulation, high chemical stability, and corrosion resistance. The melting point of alumina ceramics is 2072�°C, the Rockwell hardness is 80-90, the compressive strength is 2000-2160MPa, the bending strength is 280-310 MPa, the thermal conductivity is 20-30 W/mK, and the thermal expansion coefficient is 7-8x10^-6/°C. Alumina ceramics are widely used in high-temperature ceramics, such as making high-temperature crucibles, refractory furnace tubes, special wear-resistant materials, circuit substrates, transparent armor, missile hoods, radar covers, etc.

Alumina ceramics is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness. High purity alumina ceramics are ideal for environments where resistance to wear and corrosive substances are required. Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential. Alumina ceramic is the material of choice for alumina wear parts. The proven wear and heat resistance of alumina wear parts makes them ideal for the manufacture of wear-resistant components. Alumina has a high melting point, high hardness, although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity. Good chemical stability of alumina leads to high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Testing has shown that the low chemical solubility of alumina ceramics components makes them highly resistant to chemical corrosion. This is what makes high purity alumina the material of choice for components in a wide range of industrial applications. Alumina Ceramics are generally white and the color is derived from either the sintering additives or impurities in the raw materials. We make and supply alumina ceramic grinding media, abrasion ceramic lining and alumina ceramic parts & components. We also supply zirconia ceramics.
