Description
Alumina ceramic tube is with high temperature resistance, insulation, corrosion resistance, good air tightness, and good rapid cooling and rapid heating.
Classification
Alumina ceramics are divided into two types: 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 into 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.
Molding Method
There are many methods for forming alumina ceramic products, such as dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing. In recent years, molding technology methods such as filter press molding, direct solidification injection molding, gel injection molding, centrifugal grouting and solid free molding have been developed at home and abroad. Different product shapes, sizes, complex shapes and precision products require different molding methods.
