Wholesale of Industrial-grade Magnesium Oxide Powder

Industrial-grade magnesium oxide, commonly known as “bitter earth”, is a fine white or light yellow powder and belongs to alkaline oxides. This product is made from high-purity magnesite as raw material and refined through high-temperature calcination process. It features high chemical purity, adjustable activity and excellent heat resistance. It is an indispensable key raw material in numerous industrial fields such as refractory materials, building materials, chemical engineering, and environmental protection.

Key features and indicators

Important Note: The above are general specifications. We can customize products with different activities, purities, particle sizes and bulk densities according to your specific process requirements.

Application field

Refractory materials and ceramic industry

• Refractory materials: They are the main raw materials for manufacturing magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks and unshaped refractory materials, providing extremely high refractoriness (>2800℃) and excellent resistance to slag erosion.
• Ceramics: Used as a flux for ceramic bodies and glazes, it can effectively lower the sintering temperature and improve product performance.

Environmental Protection and Agriculture

• Environmental treatment: As an efficient neutralizer, it is widely used in the treatment of acidic wastewater and waste gas. It can effectively remove heavy metal ions and adjust the pH value of the system.
• Agriculture: Used as an animal feed additive to supplement essential magnesium elements; It can also be used as a fertilizer and soil conditioner to correct soil acidity.

Chemical and building materials industry

• Chemical intermediates: They are important precursors for the production of magnesium sulfate, magnesium carbonate, magnesium hydroxide and other magnesium salts.
• Building materials: It is used in the production of magnesium cement (Sorrell cement), lightweight partition boards, fireproof boards, etc., providing excellent fireproof, thermal insulation and sound insulation properties.

Packaging and storage and transportation

• Packaging specification: The standard packaging is 25kg per bag (using moisture-proof packaging with inner plastic and outer woven fabric). We also support a variety of packaging solutions ranging from 500kg ton bags to small batches of 25kg per bag.
• Storage conditions: It must be stored in a cool, dry and well-ventilated warehouse, avoiding being kept together with acids and damp items. Moisture absorption and caking must be strictly prevented.
• • Transportation Matters: This product is non-hazardous. During transportation, it should be protected from rain, moisture and packaging damage.
