As an expert manufacturer of ceramics, Innovacera has a complete range of advanced technical ceramics for a wide variety of applications.

Innovacera provides electronic ceramic substrate including Al2O3 (Alumina substrate) and AlN (Aluminum Nitride substrate). These ceramic substrate have good mechanical strength and abrasion resistance, high thermal conductivity , very stable in high temperature and corrosive chemical and excellent electrical insulation.

Substrates made from Alumina Ceramics

Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, isostatic pressing and extrusion productive technology etc.
