Wide‑ranging Applications of Direct‑Process Magnesium Oxide:
Direct‑process magnesium oxide is produced by high‑temperature calcining natural magnesite ore. Thermal decomposition of the ore drives off carbon dioxide and forms magnesium oxide. The controlled process guarantees good reactivity, low impurities and consistent particle‑size distribution.
Reaction Equation: MgCO3 → Heat MgO + CO2
Magnesium Oxide readily absorbs moisture and carbon dioxide from the surrounding environment. It reacts with these substances to generate magnesium hydroxide and magnesium carbonate. Thanks to this characteristic, it performs excellently in scenarios demanding chemical reactivity and adsorption capacity. Benefiting from its outstanding thermal stability and inherent alkalinity, magnesium oxide can also serve as a reliable refractory raw material and acid‑neutralizing agent.
