According to different needs from different customers, raw material of the customized alumina ceramic are strictly controlled in order to ensure the ceramic not only takes on good wear-resisting, corrosion-resistant. But also rich size, the service life is much longer.
The customized alumina ceramic is characterized by high strength, high hardness. Heat-resistance, corrosion rresistant, anti-pressure, good insulation property.
High Purity 99.5% Alumina Ceramic Pipe
1. High voltage
2. High temperature resistant
3. Corrosion resistant
4. Good strength
High purity 99.5 alumina ceramic pipe, open both end or closed one end
Alumina (Al2O3)
Is a hard, chemically resistant material and has the ability to withstand high temperatures in aggressive environments. It also possesses a high melting Point, strong hardness, making it a good material to withstand high temperature And chemical corrosion. We offers Alumina with various purity levels, including 99.8% And 99.0%. The level of purity, grain size, and density required is dependent on The application and the component configuration.
Features:
1 High dielectric properties.
2 Extreme wear and abrasion resistance.
3 Chemical corrosion resistance under high temperature.
4 Extreme high temperature stability under reducing, inert And high vacuum condition under high temperature up to 1800C.
5 Gas tight for many applications to provide protective atmospheres Or high vacuum at high temperature to eliminate contamination or impurity.
