What is magnesium oxide commonly used for?
Industrial magnesium oxide powder(MgO), also known as magnesia, is a white, hygroscopic solid with a high melting point and excellent thermal and electrical insulation properties. Due to Industrial magnesium oxide powder's chemical stability, alkalinity, and refractory nature, it has widespread applications in medicine, industry, agriculture, and environmental management. Below is an expanded overview of its key uses.
1. Medical and Pharmaceutical Applications
Antacid and Digestive Aid
Industrial magnesium oxide powder is commonly used in over-the-counter antacids (e.g., Milk of Magnesia) to neutralize excess stomach acid, providing relief from heartburn, acid reflux, and indigestion.
Industrial magnesium oxide powder reacts with hydrochloric acid (HCl) in the stomach to form magnesium chloride (MgCl₂) and water, reducing acidity.
Laxative for Constipation Relief
In higher doses, Magnesium Oxide Powder Industrial acts as an osmotic laxative, drawing water into the intestines to soften stool and stimulate bowel movements.
Magnesium Oxide Special Industrial Grade Often prescribed for short-term relief of constipation but should be used cautiously to avoid electrolyte imbalances.
Magnesium Supplementation
Magnesium Oxide Powder Industrial is used in dietary supplements to prevent or treat magnesium deficiency, which can cause muscle cramps, fatigue, and irregular heart rhythms.
However, Magnesium Oxide Powder Industrial has lower bioavailability compared to other forms like magnesium citrate or glycinate, meaning the body absorbs it less efficiently.
2. Industrial and Manufacturing Uses
Refractory Material for High-Temperature Applications
Due to its extremely high melting point (~2,800°C or 5,072°F), Magnesium Oxide Powder Industrial is a key component in:
Furnace linings (steel, glass, and cement industries)
Crucibles for molten metal handling
Kiln bricks in ceramics manufacturing
Industrial High Purity Magnesium Oxide provides thermal insulation and chemical resistance against corrosive slags and metals.
Construction and Building Materials
Industrial High Purity Magnesium OxideAdded to Portland cement to improve heat resistance and durability.
Industrial High Purity Magnesium OxideUsed in fireproof panels, wallboards, and insulation materials due to its flame-retardant properties.
Electrical Insulation
Magnesium Oxide Special Industrial Grade is an excellent electrical insulator and is used in:
Heating element insulation (e.g., industrial heaters, electric stoves)
Thermocouple tubing for high-temperature measurements
3. Agricultural and Animal Nutrition
Soil Amendment for Crop Production
Corrects magnesium-deficient soils, which can lead to poor plant growth and yellowing leaves (chlorosis).
Often applied as magnesium lime (dolomite) to balance soil pH while supplying Mg.
Livestock and Poultry Feed Supplement
Magnesium Oxide Special Industrial Grade Added to animal feed to prevent magnesium deficiency, which can cause:
Grass tetany in cattle (a potentially fatal condition due to low Mg levels)
Reduced growth and egg production in poultry
4. Environmental and Chemical Applications
Wastewater and Pollution Control
Magnesium Oxide Special Industrial Grade Used in industrial wastewater treatment to:
Neutralize acidic effluents (e.g., from mining operations)
Precipitate heavy metals (e.g., lead, arsenic) for safer disposal
Flue Gas Desulfurization (FGD)
In coal-fired power plants, MgO helps remove sulfur dioxide (SO₂) from emissions, reducing air pollution.
Fireproofing and Safety Materials
Incorporated into fire-resistant coatings, cables, and construction materials to enhance flame retardancy.
5. Food and Consumer Products
Food Additive (E530)
Industrial High Purity Magnesium Oxide Acts as an anti-caking agent in powdered foods (e.g., salt, spices, powdered milk).
Industrial High Purity Magnesium Oxide Also used as a pH regulator in food processing.
Cosmetics and Personal Care
Found in baby powders, bath salts, and skincare products for its moisture-absorbing properties.
