Aluminum oxide ceramics have a series of excellent properties such as high mechanical strength, high insulation resistance, high hardness, wear resistance, corrosion resistance, and high temperature resistance. They are widely used in various industries such as ceramics, textiles, petroleum, chemical industry, construction, and electronics, and are currently the most widely used and best-selling new ceramic material among oxide ceramics.
Generally, alumina ceramics are divided into two categories: high alumina ceramics and corundum ceramics. High alumina ceramics are ceramics mainly composed of Al2O3 and SiO2, with Al2O3 content exceeding 45%. As the Al2O3 content increases, all performance indicators of high alumina ceramics are improved; Due to the different main crystal phases in the porcelain body, it can be further divided into corundum porcelain, corundum mullite porcelain, mullite porcelain, etc. According to the different content of Al2O3, it is commonly referred to as 75 porcelain, 80 porcelain, 85 porcelain, 90 porcelain, 92 porcelain, 95 porcelain, 99 porcelain, etc. High alumina ceramics have a wide range of applications, in addition to being used as electric vacuum devices and device ceramics, they are also widely used to manufacture thick film and thin film circuit substrates, spark plug ceramics, textile ceramics, whiskers and fibers, abrasives, grinding tools and ceramic knives, high-temperature structural materials, etc; The most widely produced, sold, and applied alumina ceramic in the market is corundum ceramic with an Al2O3 content of over 90%.
