Magnesium Oxide

Is magnesium oxide soluble in water?

Magnesium oxide is almost insoluble in water at room temperature, with only trace dissolution. It reacts slowly with water to form magnesium hydroxide, appearing turbid, and is also insoluble in organic solvents such as alcohol. Owing to its insolubility and stable properties, it is widely used in chemical industry, environmental protection, food and feed additives, etc.

Food Additives

Food-grade magnesium oxide is used as an acidity regulator, anti-caking agent, nutritional fortifier, and flour treatment agent.It can be applied in dairy products, baked goods, health products, beverages, etc., to supplement magnesium, prevent caking, and adjust the pH of the system.

Pharmaceuticals & Health Products

Pharmaceutical-grade magnesium oxide features high purity and low impurities.It is mainly used in antacids, gastric mucosa protectants, and laxatives, and also as a magnesium supplement in calcium tablets, multivitamins, and other health products to neutralize stomach acid and relieve gastric discomfort.

Agriculture & Feed

Feed-grade magnesium oxide serves as a magnesium supplement to improve animal metabolism, increase milk yield and meat quality.In agriculture, it can be used as a soil conditioner to adjust soil pH and supplement medium and trace elements.

Electronic Materials

High-purity magnesium oxide has excellent insulation, thermal conductivity and stability.It is used in electronic ceramics, magnetic materials, thermistors, silicon steel sheet coatings, cable insulation materials, etc., and is an important functional material for high-end electronic and electrical products.

Chemical Catalysts

Magnesium oxide is used as a catalyst support, catalyst, adsorbent, and decolorizing agent.It plays roles in catalysis, adsorption and stabilization in organic synthesis, oil refining, dye intermediates, resin curing and other fields.

Refractory Materials

Magnesium oxide has a high melting point, high temperature resistance and strong thermal stability, making it a core raw material for high-end refractories.It is mainly used in refractory bricks, castables, furnace repair materials, refractory coatings and magnesium-carbon bricks for steelmaking furnaces, cement kilns and glass kilns.

Rubber Industry

Magnesium oxide acts as a vulcanization activator, reinforcing agent and anti-scorching agent, which can improve the tensile strength, heat resistance and wear resistance of rubber.It is widely used in rubber products such as tires, hoses, belts, rubber shoes and seals.

Desulfurization & Water Treatment

Magnesium oxide is used as an acid neutralizer and desulfurizing agent for flue gas desulfurization and industrial acid wastewater treatment.It can neutralize acidic substances and remove heavy metal ions, with mild reaction, high safety and low scaling tendency.

Stable Chemical Properties

Magnesium oxide is chemically stable, with excellent high temperature resistance and strong corrosion resistance. It does not decompose easily under high temperature and is suitable for various harsh working conditions.

Good Fluidity & Processability

Magnesium oxide features strong adsorption capacity, good fluidity, easy dispersion and processing, making it ideal for use as an additive and filler.

High Purity & High Quality

Magnesium oxide offers stable performance, high purity and low impurity content. High-quality magnesium oxide has good whiteness and uniform particle size, ensuring strong product stability.

Wide Range of Applications

Non-toxic and environmentally friendly, magnesium oxide is widely used in food, pharmaceutical, rubber, plastic, refractory, agricultural and many other industries.

Q1: What are the uses of magnesium oxide?

Magnesium oxide is commonly used as a magnesium supplement, antacid, nutritional additive and mineral raw material in medicine, food and feed. It can also be used as a flame retardant and refractory material in rubber, plastics, etc. In addition, it can be used for environmental desulfurization, water treatment, chemical catalysts and agricultural magnesium fertilizer.

Q2: What's the benefit of taking magnesium oxide?

Magnesium oxide can neutralize stomach acid, relieve excessive stomach acid and stomach discomfort. It also has a mild laxative effect to improve constipation. Meanwhile, it contributes to bone health, helps maintain stable heart rhythm and supports post-exercise recovery.

Q3: What are the side effects of magnesium oxide?

Long-term use of magnesium oxide may cause electrolyte imbalance. It can increase the burden on the kidneys in people with renal insufficiency, so excessive and long-term use should be avoided.Large amounts of magnesium oxide entering water bodies can alter water quality and pollute the environment.Adequate protection should be taken during industrial use, and excessive abuse must be avoided.
