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. Temperature resistance:excellent electrical performance, low leakage current under high temperature conditions, High safety,Has been widely applied to the elements heating in air.
  2. Filling effect:Good flow properties, better density when filled into heat pipe, therefore good thermal effects.
  3. No Silicone oil added: greatly extend the life of product in high-temperature environment.
