Fused Magnesium Oxide

Fused Magnesium Oxide Description

Fused Magnesium Oxide Powder is made from selected high-purity magnesia that undergoes melting in an electric arc furnace at ultra-high temperatures above 2800°C, followed by controlled cooling, crushing, and classification. The fusion process transforms it into a dense crystalline structure with superior purity and stability. This powder exhibits outstanding high-temperature resistance, excellent dielectric strength, and remarkable thermal conductivity, making it essential for demanding applications such as electric heating elements, high-performance refractories, and advanced ceramics.
