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