Electrical grade magnesia (EGM) powder is used as electrical insulation filler between the coil and the outer sheath in heating elements. EGM has good thermal conductivity and high electrical resistivity at elevated temperatures. 

EGM powders destined for low temperature heating elements use as main raw material Dead burned Magnesia with low iron content, specific SiO2/CaO ratio and other special physiochemical characteristics.

EGM powders destined for high temperature heating elements use as main raw material FUSED MAGNESIA which is produced by fusing special grade Caustic Calcined Magnesia.

Electrical grade Magnesia is widely used in applications in both the domestic and industrial heating element manufacturers. Its markets cover the following applications: 

  • Heating elements used in domestic appliances (cookers, dishwashers, washing machines, etc);
  • Heating elements for industrial applications (galley products, railway heating, industrial boilers, etc);
  • Automotive applications (diesel engine glow plugs and friction products);
