High temperature electrical grade magnesium oxide (mgo) for heating element

High Temperature Magnesia Powder

Our High Temperature Magnesia Powder is made of fused magnesium that contains more than 98% MgO, firstly grinned, secondly added additives, and thirdly proceeded with high temperature calcinations. The product has following features:

1. ：excellent electrical performance, low leakage current under high temperature conditions, High safety，Has been widely applied to the elements heating in air.
2. ：Good flow properties, better density when filled into heat pipe, therefore good thermal effects.
