Advantages of alumina ceramic tube in industry
The key application of industrial ceramic tube is in the production and manufacturing of power electronic technology industry, such as as the casing of high frequency and high power rectifier tube, electric vacuum tube power switch, etc. Laminated glass was originally used as the raw material of rectifier tube and tube type, but suffered from the large dielectric loss of the raw material itself and rapid heating, which is very easy to cause tube and tube cracking. At this stage, the tube and tube type used in high-power electronic devices is all three. Aluminum oxide (Al203) porcelain.
Alumina ceramic tube have the advantages of high impact toughness, good dielectric strength, low high frequency loss, high electrical and compressive strength, heat resistance, heat shock resistance, etc., and have the unmatched advantages of glass. It is suitable for high power on the market. Electron tube.
Alumina ceramic tube has excellent wear resistance and long service life. The surface is smooth and the coefficient of friction is low. It has low bulk density and light weight; it can resist the corrosion of various acids, alkalis and salts, and its hardness is second only to diamonds. Low coefficient of thermal expansion and thermal conductivity, working temperature up to 1800℃
