A. Alumina ceramics can be mainly used for protection tubes and insulating tubes of thermocouple thermometers for temperature measuring instruments.
B. At the same time, it can also be used in the furnace tubes of industrial resistance furnaces, experimental electric furnaces, and heat treatment furnaces.

 Industrial Alumina Ceramic High Temperature Furnace Tube/Pipe


High-purity alumina ceramics are ceramic materials with an Al2O3 content of more than 99.9%. Because their sintering temperature is as high as 1650-1990 ℃, and the transmission wavelength is 1-6 μm, they are generally made into molten glass to replace platinum crucibles; use its light transmittance And it can be used as a sodium lamp tube with alkali metal corrosion resistance; it can be used as an integrated circuit substrate and high-frequency insulating material in the electronics industry.


Alumina Ceramic


99 alumina porcelain material is used to make high temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve discs; 95 alumina porcelain is mainly used as corrosion-resistant and wear-resistant parts; 85 porcelain Because it is often mixed with some talc, the electrical performance and mechanical strength are improved, and it can be sealed with metals such as molybdenum, niobium, and tantalum, and some are used as electrical vacuum devices.
