  Alumina ceramic material Property. Alumina ceramics is an alumina (Al2O3) as a main component a ceramic material; it divided into high purity type and ordinary type two kinds.   High purity alumina ceramic is Al2O3 content in more than 99.9% of the ceramic material, due to its high sintering temperature 1650-1990℃, the transmission wavelength of 1 ~ 6μm. Use of its light transmittance and resistance can be used as the alkali metal sodium lamp; used as a high-frequency integrated circuit substrate and the insulating material in the electronic industry. The Ordinary type including 99%,95% 90%,85% 75% alumina etc. Such aluminum oxide Used as refractory material and or make wear-resisting corrosion resistance of parts.

Alumina ceramics is the most widely used advanced ceramic material. its form Methods including: dry press, grouting pressure, extrusion molding method, cold isostatic pressing, injection, stretch film, hot pressing and hot isostatic pressing molding, a variety of methods.   Alumina ceramic sleeve:     Main advantages of our alumina ceramic sleeve:    (1) High wear resistance, high temperature resistance    (2) High intensity and high hardness    (3) Long life    (4) Resistant to creep and mechanical stresses    (5) Low maintenance cost    (6) Corrosion resistance    (7) Performs in high temperature conditions    (8) Especially suit to used in high temperature, heavy duty and oil difficult working environment    (9) Range of sizes available.   Alumina ceramic Material technical parameter.
