Difference between light magnesium oxide and heavy magnesium oxide

Magnesium oxide is an ionic compound composed of magnesium and oxygen, belonging to basic oxide. Commonly known as bitter earth, also known as magnesia. The chemical type MgO has a high fire resistance and insulation performance, is slightly soluble in water, and is placed in the air. It is easy to absorb water and gas and gradually becomes basic magnesium carbonate and large crystalline fused magnesia. Therefore, before and after use, attention should be paid to sealed storage during transportation, and stored in a dry and ventilated environment.

Although magnesium oxide is not often used in our life, it is an important material in many fields.

In the chemical industry, magnesium oxide is the raw material for producing other chemical products. In the construction industry, it can be used to manufacture artificial chemical floors, artificial marble heat-proof panels, soundproof panels, plastics, etc. It can be used as a standard for white pigments. It can be used for the determination of coal. In addition, magnesium oxide can be used as a flame retardant, which is a traditional flame retardant material.

Magnesium oxide has a wide range of uses and varieties.

Generally, magnesium oxide can be divided into heavy magnesium oxide and light magnesium oxide. Heavy magnesium oxide can be divided into heavy burnt powder and light burnt powder according to different burning intensity, and light burnt powder can be divided into building material powder and desulfurization powder.

Light magnesium oxide is a chemical product with white color, high content and fluffy volume. The appearance is white amorphous powder.

Heavy magnesium oxide is the product of ore burning, with compact volume and white or beige powder. It is easy to combine with water and absorb water in the air. It is easy to solidify and harden after mixing with magnesium chloride solution.

Light magnesium oxide and heavy magnesium oxide have different application fields.

Light magnesium oxide is mainly used in the production of rubber products and neoprene adhesives. In rubber manufacturing, magnesium oxide acts as an acid absorbent and accelerator, and in ceramics and enamel, it plays a role in reducing the sintering temperature. It can be used as a filler in the manufacturing of grinding wheel and paint, as a whitening agent or refined sugar decolorizer in food processing, and as fertilizer and feed additive for livestock in agriculture

Heavy magnesium oxide can be used to produce magnesium salt in the chemical industry, and in the construction industry to manufacture artificial chemical floors, artificial marble heat-proof panels, soundproof panels, and plastic industry as filler.

In addition, there are many kinds of magnesium oxide, including 65 powder, 70 powder, 75 powder, 80 powder, 85 powder, 90 powder, etc. When purchasing magnesium oxide, the seller should be contacted first to determine the type and content required.
