Introduction of alumina ceramic materials:
Alumina ceramic is a ceramic material mainly composed of alumina (Al2O3). Alumina ceramics have a series of excellent properties such as high mechanical strength, high insulation resistance, high hardness, wear resistance, corrosion resistance, high temperature resistance and light weight. It is widely used in various industries such as textile, petrochemical, construction, machinery, electronics, biomedicine, etc. It is the most widely used ceramic material in oxide ceramics. Alumina ceramics are classified into high-purity type and ordinary type. The high-purity alumina ceramic is a ceramic material having an Al2O3 content of 99.9% or more. Since the sintering temperature is as high as 1650-1990 ° C and the transmission wavelength is 1 to 6 μm, molten glass is generally prepared to replace platinum rhodium. It is used as a sodium lamp tube due to its light transmittance and alkali metal corrosion resistance. It can be used as an integrated circuit substrate and high frequency insulating material in the electronics industry. Ordinary alumina ceramics can be divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain, etc. according to different Al2O3 content. Sometimes the Al2O3 content is 80% or 75%, which is also classified into ordinary alumina ceramic series. 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 and water valve sheets. 95 Alumina Porcelain is mainly used as a corrosion-resistant and wear-resistant part. In 85 porcelain, due to the incorporation of part of talc, the electrical properties and mechanical strength are improved, and it can be sealed with metals such as molybdenum, niobium and tantalum, and some are used as electric vacuum device devices.
