Magnesium oxide – fused

Magnesium Oxide (MgO) - fused, also known as FM, is produced by fusion of magnesium oxide (MgO) in electric arc furnaces at temperatures > 2800°. Due to its very low chemical activity, high purity, high temperature resistance and low conductivity, fused magnesite is used as an insulating filler and in refractory materials.

Qualities: FM is available in various purities and grain sizes.
