Magnesium Oxide Wafer Description

Magnesium Oxide WaferMagnesia Ceramic is a ceramic material consisting of at least 90% of Magnesium Oxide(MgO). It demonstrates good mechanical strength and operates well when uniformly heated or cooled and thermal shock is avoided. It offers superior performance to Alumina, being stable to 2200°C.

MgO wafer can be fabricated in round or square shape, with a SEMI flat or without flat, one side polished or two sides polished, size from 10 x10 mm to 2 “, thickness range from 0.4, 0.5, 1 to 2 mm, surface are epi polished with low surface roughness. We have twin-free and defect-free MgO substrate with various orientations , and , and a high precision surface finish.
