MAGNESIUM OXIDE
Magnesium oxide is renowned for its unparalleled thermal resistance, with a melting point of 2,852°C (5,166°F)-one of the highest among metal oxides. This property stems from its ionic crystal structure (rock-salt lattice), which maintains integrity even under extreme heat. In refractory applications, such as steelmaking furnaces or cement kilns, MgO linings exhibit minimal thermal expansion (CTE ~13.5×10⁻⁶/K at 25–1,000°C) and resist slag corrosion.

Refractory Materials: MgO Is Essential For Furnace Linings In Steel, Cement, And Glass Industries (Withstands Temperatures Up To 2,800°C). Its High Melting Point And Thermal Stability Reduce Energy Consumption In High-Heat Processes.Environmental Protection: Used in flue gas desulfurization (FGD) to neutralize acidic pollutants (e.g., SO₂) from coal-fired plants. Also immobilizes heavy metals in soil/water treatment.
