1. Good thermal conductivity, high insulation strength and high resistivity, low dielectric loss, and dielectric constant is 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.The cost of production is greatly saved
Alumina ceramics are also called precision ceramics, special ceramics, or high-tech ceramics. It uses highly selected raw materials and is produced according to a special manufacturing process, which can precisely control the chemical composition and ceramics with excellent properties.
