High Purity Alumina Series Products

Single-crystal Alumina

Single Crystalline Alumina / Single Crystalline Aluminum Oxide

Single crystal alumina is easier to form line contact and surface contact because heat energy passes directly through single crystal, so it is easier to form thermal conductivity channel, and has obvious advantages in thermal conductivity. Our single crystal alumina product has high melting point, good stability, small specific surface area, clean surface, no residual metal impurities and burr, high sphericity, high α phase content, low surface oil absorption value, single crystal transparent, in silicone grease system viscosity reduction is obvious, its thermal conductivity and electrical insulation excellent.

It can be used in lithium battery ceramic diaphragm coating, thermal interface materials, thermal conductivity engineering plastics, high thermal conductivity aluminum coated copper plate, ceramic filter coating, etc.
