Product Details
alumina ceramic
The product range includes ceramic water valve plates for sanitary ware, ceramic sealing rings for water pumps and machinery, wear-resistant ceramics, textile machinery porcelain parts, electronic insulation porcelain parts, ceramic plungers and ceramic shaft sleeves, ceramic rods, rods, plates, and other structural ceramic products, as well as various special-shaped porcelain parts for other industry applications,. Alumina ceramic is the most common advanced precision ceramic material and also a relatively traditional material. High purity alumina ceramics, as an excellent ceramic material, have been widely used in many industries.
Alumina ceramics can be divided into multiple application levels based on their alumina content. Among them, 99% alumina ceramic materials are used to make plungers, sealing rings, and special wear-resistant materials, such as ceramic structural components, water valve plates, etc; 95% -96% alumina ceramics are mainly used as corrosion-resistant and wear-resistant components and circuit substrates.
Performance of alumina ceramics:
1. Good thermal conductivity, high insulation strength, resistivity, low dielectric loss, and dielectric constant generally between 8-10;
2. It has good conductivity, mechanical strength, and high temperature resistance, and can be made into high-temperature structural ceramics;
3. Good insulation, low high-frequency loss; In terms of wear resistance, the hardness can reach nine degrees Mohs hardness; Low coefficient of thermal expansion, good thermal conductivity, and strong heat resistance.
Color of alumina:
Alumina ceramics may vary in color depending on their alumina content. 95% -96% alumina porcelain is milky white, while 99% alumina porcelain is yellow.
Density of alumina:
Alumina ceramics may vary in density depending on their alumina content. 95% -96% alumina ceramics are 3.7-3.8g/cm3, while 99% alumina ceramics are 3.8-3.9g/cm3.
