Product content

The wear-resistant alumina ceramic ring has a wide range of uses. With its high mechanical strength and high insulation resistance, it can be used as vacuum devices, device porcelain, thick film and thin film circuit substrates, thyristor and solid circuit shells, and spark plugs. Insulators, etc. With its high strength and hardness, it can be used as abrasives, textile ceramics, knives, etc. In addition, it can be used to produce good transparent ceramics, which can be used as sodium light tubes, infrared detection materials, etc. With its good chemical stability, it can be used as chemical and biological ceramics, artificial joints, replacing platinum crucibles, catalytic carriers, and aviation and magnetic fluid power generation materials. With the development of science and technology and the improvement of manufacturing technology, new varieties continue to appear, and they will be more and more used in modern industry and modern science.

Product parameters

The ceramic layer contains more than 390% AL2O, and the acid resistance is 96-98%, which is the same as that of high corundum porcelain. Corrosion resistance is ten times higher than stainless steel, wear resistance is equivalent to tungsten-cobalt cemented carbide, ten times higher than steel, and can work for a long time below 900°C. The performance parameters can be seen in Table 1-7.
