Introduction And Application Of Alumina Ceramic

Alumina Ceramic is a kind of ceramics with a wide range of uses. Because of its superior performance, in the modern society has been more and more widely used to meet the needs of daily and special performance.

High Purity Alumina ceramics A12O3 content is more than 99.9% of the ceramic material, due to its sintering temperature up to 1650-1990℃, transmission wavelength of 1~6um, generally made of molten glass to replace platinum crucible: using its light transmission and alkali metal corrosion resistance as sodium lamp tube; It can be used as integrated electric subgrade board and high frequency insulating material in electronics industry.

Ordinary alumina ceramics are divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties according to the content of AI203. Sometimes, AI203 contains 80% or 75% and is classified as ordinary alumina ceramics series. 99 alumina porcelain material is used to make high temperature crucible, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve plates; Alumina porcelain is mainly used for corrosion resistance, wear resistance parts; The 85 porcelain is often mixed with talc, which improves the electrical property and mechanical strength. It can be sealed with molybdenum, niobium, tantalum and other metals, and some are used as electric vacuum devices.

Alumina ceramics have certain advantages in high temperature resistance, corrosion resistance, wear resistance, erosion resistance and other characteristics, is applied to the harsh working environment of metal/organic polymer materials ideal replacement material, for the traditional industrial transformation, emerging industries and high-tech development can provide a huge role.
