High Purity Magnesium Oxide Manufacturer & Free Sample- CAS 1309-48-4

Magnesium Oxide Product Overview

Light magnesium oxide (MgO Light) is a white powdery inorganic compound with the chemical formula MgO. Known for its low density, high purity, and large surface area, it is produced by high-temperature calcination of magnesite or precipitation from brine. It has a wide range of uses and is an indispensable material in the industrial and food sectors.

Magnesium oxide specifications

Magnesium oxide characteristics:

1. Physical Properties: White or light yellow powder with a loose texture, large volume, and low density (0.3–0.5 g/cm³). Calcination temperature is approximately 700–1000°C, resulting in small crystals and a large specific surface area.

2. Chemical Properties: Chemical formula: MgO. Purity generally ranges from 85%–96%, with high purity reaching over 99%. Highly reactive, it reacts quickly with water and acids. It is highly alkaline and has a neutralizing effect on acids.

3. Performance Characteristics: High reactivity and excellent adsorption. It has strong adsorption capacity for moisture, carbon dioxide, and hazardous substances.

Light magnesium oxide is a highly reactive alkaline material with a large specific surface area and outstanding adsorption and reactivity properties. It is widely used in building materials, agriculture, environmental protection, chemicals, and pharmaceuticals.

Magnesium oxide uses:

1. Refractory Materials: Due to its high melting point (>2800°C) and strong refractoriness, magnesium oxide is an important raw material for refractory bricks, electric furnace linings, and metallurgical furnace linings. It is commonly used in high-temperature equipment such as steel smelting, non-ferrous metal smelting, glass, and cement kilns.

2. Building Materials: As a magnesia-based cementitious material, it can be combined with magnesium chloride and other materials to form "magnesium oxychloride cement," which is used in fireproof panels, partition boards, ceilings, and floor tiles. Its lightweight, fireproof, and moisture-resistant properties make it widely used in green building materials.

3. Chemical Raw Materials: It is used to prepare magnesium salt compounds (such as magnesium sulfate, magnesium carbonate, and magnesium chloride).
It is used as a filler and reinforcing agent in rubber and plastics, improving the wear and heat resistance of the products. It can also be used as a catalyst, adsorbent, and desiccant.

4. Environmental Protection: In wastewater treatment, it is used as a neutralizer to adjust the pH of acidic wastewater. It can also be used in flue gas desulfurization, replacing limestone and reducing sulfur dioxide emissions. Adsorbent: Treats heavy metal ions or organic pollutants.

5. Agriculture: As a magnesium fertilizer, it replenishes magnesium in the soil and promotes crop photosynthesis. It regulates soil acidity and improves crop yield and quality.

6. Pharmaceutical and Food: Pharmaceutical-grade magnesium oxide can be used as an antacid to relieve excessive stomach acid. It can also be used as a laxative and magnesium supplement. Food Additive: It can be used as a decolorizer, pH adjuster, or nutritional supplement (magnesium source).

7. Electrical and Electronics: Due to its excellent insulating properties, it is used in cable fillers and heating element insulation. In the electronics industry, it can be used as a raw material for high-performance ceramic materials.

8. Other: It has certain uses in papermaking, sugar refining, glass, and coatings. In the aerospace industry, it is used to prepare lightweight, high-temperature structural materials.
