electrical grade magnesium oxide powder

Established in 2007,we can produce about 5000 MT magnesium oxide powder each year. Our products is the very important materials in the field of electrical heating element manufacturing. Until now,we have developed five types of electrical grade modified magnesium oxide powders,including high temperature powder SD-8,medium temperature powder SD-99Aand SD-99, Mid-low temperature powder SD-6, Low temperature powder are widely used in different technical conditions and fields.

SD-8 IS the high temperature magnesium powder with light silicon treatment, mainly used in air heating elements of medium or high wattage loading. It can stand 1050oC annealing and requires immediate sealing. This kind of powder is specially used for the manufacture of hotplate.
