Description

Product Detail

Magnesium oxide (MgO) is a common inorganic compound composed of magnesium and oxygen. It appears as a white powder or crystal at room temperature. It possesses a high melting point (approximately 2852°C), strong alkalinity, and high-temperature resistance. It is widely used in refractory materials, medicine, and environmental protection.

I. Basic Properties and Structure
Physical Properties 1.
It appears as a white, odorless powder with a density of 3.58 g/cm³ and high hardness.
It has extremely high melting and boiling points, making it a high-quality high-temperature refractory material.
It is slightly soluble in water, and its aqueous solution is weakly alkaline.

II. Main Applications
Refractory Materials 1.
Due to its high-temperature resistance, it is commonly used in metallurgical furnace linings, crucibles, refractory bricks, and other applications, accounting for over 60% of industrial use.

Pharmaceuticals and Food 2.
In pharmaceuticals, it is used as an antacid to neutralize stomach acid (e.g., as an ingredient in stomach medicine);
In food additives, it is used to adjust pH or as a nutritional supplement (magnesium supplement).
Environmental Applications 3.
Treats acidic wastewater and neutralizes pollutants such as sulfuric acid and hydrochloric acid;
Adsorbs heavy metal ions and purifies industrial waste gas.
Agriculture and Horticulture 4.
Improves acidic soils and adjusts pH to a suitable range for crop growth;
Uses magnesium fertilizer as a nutritional supplement for plants.
Industrial Additives 5.
Filler in rubber and plastics, improving heat and wear resistance;
Flux in ceramic and glass production;
Key component of cable insulation.
