Our Fused Magnesium Oxide (Electrical Grade) powder is manufactured by the electric melting method (Item No.:OX12H-2N5). The raw materials of the product are from seawater, not minerals, resulting in low impurities. The product has excellent high-temperature resistance and electrical insulation. Therefore it is widely used in heating elements and the refractory industry.
