product manual:

Name: electric tube porcelain beads, heat pipe porcelain beads

Material: 95 alumina ceramic

Features: high temperature, high pressure, high dielectric strength, no leakage

Applicable to all kinds of metal heating pipe, heating pipe insulation

Alumina ceramics are currently divided into two types of high purity and common type. High purity alumina ceramic Al2O3 content of 99.9% or more of the ceramic material, because of its sintering temperature of up to 1650-1990 ℃, transmission wavelength of 1 ~ 6μm, generally made of molten glass to replace the platinum crucible: the use of its light And alkali-resistant metal corrosion for sodium lamp; in the electronics industry can be used as integrated circuit substrate and high-frequency insulation materials. Ordinary alumina ceramic according to Al2O3 content is divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties, sometimes Al2O3 content of 80% or 75% were also classified as ordinary alumina ceramic series. 99 alumina ceramic is used for the production of high temperature crucible, refractory tube and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve, etc .; 95 alumina ceramic is mainly used for corrosion-resistant, wear parts; Due to the incorporation of some talc, improve the electrical properties and mechanical strength, with molybdenum, niobium, tantalum and other metal sealing, and some used as electrical vacuum device devices.
