Direct‑method Magnesium Oxide finds extensive utilization in the industries specified below:
Magnesium Oxide has high affinity for moisture and carbon dioxide. It reacts to produce magnesium hydroxide or magnesium carbonate, delivering good reactivity and adsorption performance for relevant uses. Owing to its thermal stability and basic property, it can act both as refractory material and neutralizing agent.
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.
