Magnesium Oxide (Direct Method) enjoys broad application across multiple industrial sectors, key fields are listed below:
The direct‑method production relies on high‑temperature calcination of natural magnesite ore. Under intense thermal conditions, the raw ore decomposes thermally and releases carbon dioxide, yielding magnesium oxide as the final product. This carefully controlled manufacturing route delivers outstanding reactivity, low impurity levels, and uniform particle‑size distribution across batches.
Reaction Equation: MgCO3 → Heat MgO + CO2
Magnesium Oxide exhibits a strong affinity for moisture and carbon dioxide, forming magnesium hydroxide or magnesium carbonate upon reaction. This makes it an effective material for applications requiring reactivity and absorption capabilities. Its thermal stability and basic nature also allow it to function as a refractory and neutralizing agent.
