Product Description

Product Description

Magnesium Oxide, also known as magnesia, is an inorganic compound with the chemical formula MgO. Here is a detailed introduction to it:

Basic Information

• Chemical Formula: MgO
• Molar Mass: Approximately 40.30 g/mol
• Appearance: It typically appears as a white solid in its pure form.

Physical Properties

• Density: The density of magnesium oxide is about 3.58 g/cm³.
• Melting Point: It has a very high melting point of around 2852 °C. This high melting point makes it suitable for use in high-temperature applications.
• Boiling Point: The boiling point of magnesium oxide is approximately 3600 °C.
• Solubility: It is sparingly soluble in water. When it reacts with water, it can form magnesium hydroxide to a certain extent.

Chemical Properties

• Reactivity with Acids: Magnesium oxide is a basic oxide and reacts readily with acids to form magnesium salts and water. For example, when it reacts with HLC, the chemical equation is as follows: MgO + 2HCl = MgCl2 + H2O.
• Reactivity with Water: Although it is sparingly soluble in water, it can react with water to produce magnesium hydroxide. The reaction equation is MgO + H2O = Mg(OH)2.
• Thermal Stability: It is thermally stable and can withstand high temperatures without decomposing easily. This property makes it useful in refractory materials.

Production Methods

• Calcination of Magnesite: The most common method is to calcine magnesite (MgCO3). When magnesite is heated at high temperatures, it decomposes to form magnesium oxide and carbon dioxide. The chemical equation is MgCO3 → MgO + CO3↑.
• Hydrothermal Method: In the hydrothermal method, magnesium-containing raw materials react under high temperature and pressure in an aqueous solution to form magnesium hydroxide, which is then calcined to obtain magnesium oxide.

Applications

• Refractory Materials: Due to its high melting point and thermal stability, magnesium oxide is widely used in the production of refractory bricks and linings for furnaces, kilns, and other high-temperature equipment.
• Cement and Concrete: It can be used in the production of special cements and concrete additives. It can improve the strength and durability of concrete.
• Medical Field: Magnesium oxide is used as an antacid and laxative in medicine. It can neutralize stomach acid and relieve symptoms of indigestion and heartburn.
• Catalyst Support: It is often used as a support material for catalysts in various chemical reactions.
• Electrical Insulation: It has good electrical insulation properties and can be used in the production of electrical insulating materials.

Safety Considerations

• Magnesium oxide is generally considered safe. However, inhalation of its dust for a long time may cause respiratory irritation. In case of contact with eyes or skin, it should be rinsed immediately with plenty of water.

In conclusion, magnesium oxide is an important inorganic compound with a wide range of applications in many fields due to its unique physical and chemical properties.
