High Purity Alumina is a uniform fine powder characterized by highly pure and homogeneous crystal structure. It is a high-value and highly demanded product as it is the critical ingredient required for the production of synthetic sapphire. Synthetic sapphire is used in the manufacture of substrates for LED lights, semiconductor wafers in the electronics industry, and scratch-resistant sapphire glass used for wristwatch surfaces, and smartphone components. Increasingly, HPA is being used as a coating on the separator sheets in lithium-ion batteries. And the specific properties include chemical stability, high melting point, high mechanical strength, high hardness, high electrical insulation resistance and good thermal conductivity.
