Direct‑process Magnesium Oxide Powder For Construction Magnesium Cement

Our direct‑method Magnesium Oxide (MgO) is a premium inorganic compound for multiple industrial uses. It features high purity, good reactivity and broad application compatibility. As a fine white powder, it is processed from natural magnesite ore via professional calcination procedures. Strict production control secures steady batch quality and reliable performance for your production.

• High Purity: Consistent & reliable performance for varied uses
• Excellent Reactivity: Well‑matched for processes needing quick chemical reaction
• Great Thermal Stability: Strong resistance against high‑temperature environments
• Low Impurities: Very low heavy‑metal and contaminant contents
• Fine Particle Size: Supports even mixing and uniform distribution

• Premium‑Grade Feedstock: High‑quality magnesite ore is applied as the primary raw material.
• Robust Functional Performance: Capable of steady operation under rigorous industrial application requirements.
• Economical & Sustainable Manufacturing: Production process balances cost efficiency and environmental compliance.
• Low Hygroscopic Property: Minimal moisture absorption contributes to a prolonged shelf‑life.
• Multi‑process Adaptability: Suitable for deployment across numerous industrial processing routes.

• Construction Materials: Applied to manufacture magnesium‑based cement and various refractory products.
• Agriculture: Functions as soil conditioner to regulate pH value for acid soils.
• Rubber & Plastics: Serves as functional filler and reinforcing agent within rubber formulations.
• Chemical Industry: Acts as core raw material for manufacturing different magnesium salt products.
• Environmental Protection: Deployed for water treatment and flue‑gas desulfurization processes.
• Ceramics: Utilized in the production of high‑temperature ceramics and special glass.

Main processes: ammonia process, aerosol salt ablation, sol‑gel, homogeneous precipitation, thermal decomposition (magnesite/dolomite), brine method, liquid phase precipitation (brucite).

Ionic compound (Mg²⁺/O²⁻); basic oxide forming Mg(OH)₂ with water; surface defects provide strong adsorption; flame retardancy via heat absorption & insulating layer; high‑temperature resistance from high melting point and structural stability.

• Store tightly sealed in a dry, cool place; prevent moisture absorption (forms basic carbonate, reducing activity).

• Keep away from acids; do not store or transport together with acidic substances.

• Strictly differentiate grades: industrial grade is NOT for human consumption; food/pharma grades must comply with applicable standards.

• Retest activity before use if product is expired (food grade: 24 months; industrial: 12 months) or has been exposed to moisture.

• Wear dust mask, goggles, and gloves during handling; maintain good ventilation in the workplace.

• If inhaled, move to fresh air; if in eyes, rinse with plenty of water; if on skin, wash with soap. Protect from moisture and physical damage during transportation.
