conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic
electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, 200T isostatic pressing and extrusion productive technology etc.
Product Features
1. It has the characteristics of high hardness, wear resistance and corrosion resistance. It can be widely used as grinding medium in ball mill, vibration mill, planet mill and stirring mill. 99 alumina ceramic tube wear rate is small, not stained with dirt material, long service life, high grinding efficiency.
2. 99 alumina ceramic tube is made of 99 alumina ceramic tube formed by hot die casting slurry and sintered at 1500℃. It has the characteristics of high temperature resistance, high mechanical strength, good insulation performance, high electrical strength, good chemical stability, and accurate abrasion resistance and scour resistance.
3. 99 Alumina ceramic tubes are widely used in radio, electronic components, textile ceramics, ball mill lining, nodular blasting nozzle and argon arc welding gun nozzle, etc.
