High Purity MgO Powder 99.9% Magnesium Oxide Bulk Industrial Grade

Product Specification

Product Description

Magnesium oxide (MgO), with the chemical formula MgO, is a typical alkaline earth metal oxide. It appears as a white or off-white powder, odorless, tasteless, and non-toxic. It has an extremely high melting point of 2852°C and a boiling point of 3600°C. MgO exhibits low solubility in water, which slightly increases with temperature and is influenced by the presence of carbon dioxide. As an important inorganic compound, magnesium oxide finds wide applications across numerous industries due to its unique physicochemical properties.

Production Process

The preparation processes for magnesium oxide mainly include:

• Thermal Decomposition: Obtaining MgO by thermally decomposing magnesite or dolomite.
• Seawater Method: Treating seawater with hydrated lime to obtain magnesium hydroxide precipitate, which is then calcined to obtain MgO.
• Brine Method: Using brine as a raw material, adding sodium hydroxide or sodium carbonate to generate magnesium hydroxide or basic magnesium carbonate precipitate, which is then calcined to obtain MgO.

Theory

Magnesium oxide consists of Mg²⁺ ions and O²⁻ ions bound together by ionic bonds to form a lattice. It exhibits high thermal conductivity and low electrical conductivity, making it an important component of refractory materials. Additionally, MgO's stability renders it valuable in studying crystal vibration characteristics.

Packaging & Storage

• Packaging: Sealed, moisture-proof packaging materials are used to ensure the product remains dry and undegraded during transportation and storage.
• Storage: It should be stored in a cool, well-ventilated warehouse, protected from direct sunlight and high temperatures. It should also be stored separately from oxidants, acids, halogens, and other substances to prevent dangerous reactions.

Preventive Measures

• Moisture Protection: Ensure the storage environment is dry by using desiccants or placing desiccants inside containers.
• Sealed Storage: Store magnesium oxide in sealed containers to prevent exposure to moisture and carbon dioxide in the air.
• Avoid High Temperatures: Maintain the storage environment at room temperature or below to prevent MgO decomposition or degradation due to excessive heat.
• Personal Protection: Operators handling and storing magnesium oxide should wear appropriate personal protective equipment, such as dust masks, chemical safety goggles, breathable work clothes, and rubber gloves.

By following these preventive measures, the risk of chemical reactions occurring during storage and transportation of magnesium oxide can be effectively reduced, ensuring product stability and safe use.
