About Magnesium Oxide (MgO)
Magnesium Oxide (MgO) is an inorganic compound consisting of magnesium and oxygen atoms forming a white to off-white powder or granular solid. Known for its high melting point, chemical stability, and basic pH, MgO is commonly supplied in industrial-grade concentrations typically exceeding 95% purity. It is slightly soluble in water, exhibiting a basic aqueous slurry pH range of 10-12. Buyers should note that MgO should be handled with care to avoid inhalation of dust, and storage away from moisture is advisable to prevent agglomeration or reaction with acidic substances. Typical dosage rates vary by application, for instance, soil conditioning often uses MgO at several hundred kilograms per hectare to neutralize acidic soil.
Why Magnesium Oxide (MgO) Matters
In refractory manufacturing, MgO's ability to withstand temperatures beyond 2800°C enables the production of bricks and linings that maintain integrity in extreme thermal and corrosive environments. This property reduces maintenance frequency and improves furnace efficiency. In water treatment, MgO raises pH in acidic wastewater streams, neutralizing harmful contaminants and facilitating compliance with environmental discharge regulations. This ensures treatment systems can maintain optimal process conditions and safeguard downstream ecosystems.
Applications & Industries
Refractory manufacturingMgO's high melting point and chemical inertness make it critical for forming bricks and furnace linings that resist thermal decomposition and chemical attack under severe operating conditions.
Water treatment and pH adjustmentMgO neutralizes acidic waters by raising pH, preventing corrosion in piping and improving removal efficiency of metallic contaminants in industrial effluents.
