1309-48-4  Industrial

Magnesium Oxide (MgO), with the CAS number 1309-48-4, is widely used in various industrial applications due to its unique chemical and physical properties. Below is an overview of its key industrial uses

1. Refractory Materials

MgO is a critical component in the production of refractory materials, which are used to line high-temperature industrial furnaces, kilns, and reactors. Its high melting point (2,852°C or 5,166°F) and thermal stability make it ideal for these applications.

Uses

Lining of steelmaking furnaces.

Cement kilns.

Glass manufacturing furnaces.

Properties

High thermal resistance.

Chemical inertness at high temperatures.

2. Ceramics and Glass Manufacturing

MgO is used as a raw material in the production of ceramics and glass.

Uses

As a flux in glass production to improve thermal and mechanical properties.

In ceramics to enhance strength and durability.

Properties

Improves thermal shock resistance.

Reduces melting temperature of glass.

3. Chemical Industry

MgO is used as a precursor or catalyst in various chemical processes.

Uses

Production of magnesium salts (e.g., magnesium sulfate, magnesium chloride).

Catalyst in organic synthesis and petrochemical processes.

Neutralizing agent in acid waste treatment.

Properties

High reactivity with acids.

Acts as a buffering agent.

4. Environmental Applications

MgO is used in environmental protection processes, such as flue gas desulfurization and wastewater treatment.

Uses

Removal of sulfur dioxide (SO₂) from industrial flue gases.

Precipitation of heavy metals and phosphates from wastewater.

Properties

High alkalinity and reactivity with acidic gases.

Forms insoluble compounds with contaminants.

5. Construction Industry

MgO is used in construction materials, particularly in magnesium oxide boards (MgO boards).

Uses

Fire-resistant wall panels.

Sheathing and insulation materials.

Properties

Fire resistance.

Moisture resistance.

Lightweight and durable.

6. Agriculture

MgO is used as a magnesium supplement in fertilizers and soil conditioners.

Uses

Corrects magnesium deficiency in soil.

Improves plant growth and crop yield.

Properties

Slowly releases magnesium ions in soil.

Alkaline nature helps neutralize acidic soils.

7. Electrical Insulation

MgO is used as an insulating material in electrical heating elements.

Uses

Insulation in industrial heaters and cables.

Properties

High dielectric strength.

Thermal conductivity.

8. Fireproofing and Fire Retardants

MgO is used in fireproofing materials due to its non-combustible nature.

Uses

Fire-resistant coatings.

Fireproof boards and panels.

Properties

Withstands extreme temperatures.

Does not release toxic fumes when exposed to fire.

9. Rubber and Plastics Industry

MgO is used as a filler and stabilizer in rubber and plastic products.

Uses

Improves heat resistance and mechanical properties.

Acts as a curing agent in rubber manufacturing.

Properties

Enhances durability and stability.

10. Pharmaceuticals and Cosmetics

MgO is used in the production of antacids, laxatives, and cosmetic products.

Uses

Antacid for neutralizing stomach acid.

Ingredient in skincare products for its soothing properties.

Properties

Mild alkaline nature.

Non-toxic and safe for human use.

Safety and Handling in Industrial Applications

Storage Store in a dry, cool place to prevent moisture absorption.

Handling Use PPE (gloves, masks, etc.) to avoid inhalation or skin contact.

Environmental Impact MgO is generally safe and environmentally friendly, but proper disposal of byproducts is necessary.
