Talk About Where Is The Main Application Of Alumina Ceramics

Today,the editor of Alumina Ceramics Application understands where the main application of alumina ceramics is.

Where is the main application of alumina ceramics:

Alumina ceramics are currently divided into high-purity and ordinary types.High-purity alumina ceramics ceramic material with Al2O3 content above 99.9%,due to its sintering temperature as high as 1650-1990 ℃,transmission wavelength is 1 ~ 6μm,generally made of molten glass to replace platinum crucible: use its light transmission It can be used as sodium lamp in alkali metal corrosion resistance;it can be used as integrated circuit substrate and high frequency insulating material in the electronics industry.

Ordinary alumina ceramics are divided into 99 porcelain,95 porcelain,90 porcelain,85 porcelain and other varieties according to different Al2O3 content.Sometimes Al2O3 content of 80% or 75% is also classified as 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 valves,etc .;95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant components;85 porcelain Because it is often doped with some talc,it improves the electrical properties and mechanical strength.It can be sealed with metals such as molybdenum,niobium,and tantalum,and some are used as electrical vacuum device devices.

Through the understanding of the application of alumina ceramics,I hope to help you.
