Shaped alumina ceramics

Alumina ceramics have the characteristics of strength, hardness, insulation, heat conduction, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance, and high temperature strength. Alumina ceramics are currently divided into two types: high-purity type and ordinary type. Ordinary alumina ceramics are divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties according to the content of Al2O3. Among them, 99 alumina ceramic materials are used to make high-temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, Ceramic seals, etc.; 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant parts; 85 ceramics are often mixed with some talc, which improves the electrical properties and mechanical strength, and can be sealed with molybdenum, niobium, tantalum and other metals. It is used as an electric vacuum device device. High-purity alumina ceramic is a ceramic material with an Al2O3 content of more than 99.9%. Because its sintering temperature is as high as 1650-1990°C and the transmission wavelength is 1-6μm, it is generally made into molten glass to replace platinum crucible: use its light transmission It can be used as a sodium lamp tube because of its high corrosion resistance and alkali metal corrosion resistance; it can be used as an integrated circuit substrate and high-frequency insulating material in the electronics industry. Application fields: wear-resistant, corrosion-resistant and high-temperature resistant mechanical parts for precision machinery, ceramic shafts for filter pumps for aquarium equipment, ceramic plungers for high-pressure cleaners, wear-resistant, acid and alkali-resistant, high-strength ceramic shaft components for chemical, chemical and petroleum industries, etc.
