Product Overview

 

 

Alumina ceramics are divided into high-purity type and ordinary type.

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 to 6 μm, they are generally made of molten glass to replace platinum crucibles; use its light transmission It can be used as a sodium lamp tube, and 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 and other varieties according to different Al2O3 content. Sometimes those with Al2O3 content of 80% or 75% are also classified as ordinary alumina ceramic series. Among them, 99 alumina porcelain 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 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.

Product Picture

 

(1) High hardness

As determined by the Shanghai Institute of Ceramics, Chinese Academy of Sciences, its Rockwell hardness is 80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel.

 

(2) Excellent wear resistance

Measured by the Institute of Powder Metallurgy of Central South University, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. Under the same working conditions, the service life of the equipment can be extended at least ten times.

 

(3) Light weight

Its density is 3.5g/cm3, only half that of steel, which can greatly reduce the equipment load.
