Magnesium oxide

White amorphous powder. Odorless and tasteless. Hardly soluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution.

Magnesium oxide plays a very important role in promoting the synthesis of chlorophyll and improving crop quality, and can affect the growth process of plants, especially for acidified soil.The content of fertilizer grade magnesium oxide is in the range of 70%-85%, which does not require high activity, and can improve the soil and increase the magnesium content in the soil.

Magnesium oxide, commonly known as magnesia, is a white, hygroscopic, and highly refractory compound. It is widely used in industries, agriculture, and healthcare due to its diverse chemical and physical properties.

Applications

1. Industrial Uses:

   • Refractory Material: Used in furnaces, kilns, and crucibles due to its high melting point.

   • Construction: As a component in cement, plaster, and fireproof materials.

2. Agriculture:

   • Soil Amendment: Neutralizes acidic soils and supplies magnesium for plant nutrition.

   • Livestock Feed Additive: Provides essential magnesium for animal health.

3. Healthcare:

   • Antacid: Relieves indigestion and heartburn.

   • Laxative: Used in certain formulations to treat constipation.

4. Environmental Applications:

   • Flue Gas Treatment: Removes sulfur dioxide and other pollutants.

   • Water Treatment: Acts as a pH regulator and coagulant.

5. Chemical Manufacturing:

   • Precursor for producing magnesium salts and other compounds.

Benefits in Agriculture

1. Plant Health:

   • Supplies magnesium, a critical nutrient for photosynthesis and enzyme activation.

   
   

2. Soil Improvement:

   • Neutralizes acidic soils, improving nutrient availability.

   
   

Usage Recommendations

1. Soil Amendment:

   • Apply based on soil test results; typical rates range from 100–200 kg/ha.

   
   

2. Livestock Feed:

   • Add according to veterinary guidelines to meet magnesium requirements.

   
   

Storage and Handling

• Storage:

  • Store in a dry, cool, and well-ventilated area.

  • Keep away from moisture to prevent caking.

• Handling Precautions:

  • Use protective equipment to avoid inhalation of dust or contact with skin and eyes.

Safety Considerations

1. Toxicity:

   • Non-toxic when used appropriately but may irritate the respiratory system if inhaled as dust.

   
   

2. Environmental Impact:

   • Environmentally safe when applied within recommended limits.

   
   

Magnesium oxide is a versatile compound valued for its role in industrial, agricultural, and healthcare applications. Its high thermal stability and reactivity make it indispensable in numerous processes.
