Product Applications

Magnesium Oxide is a versatile inorganic material widely used in various industries due to its excellent physical and chemical properties. Key applications include:

Refractory Materials: Used as a raw material for refractory bricks, crucibles, and furnace linings in metallurgical, glass, and cement industries, thanks to its high melting point and good thermal stability.

Chemical Industry: Serves as a neutralizing agent, catalyst, and additive in the production of magnesium salts, fertilizers, and pharmaceuticals. It is also used in the treatment of industrial wastewater due to its alkaline properties.

Building Materials: Added to cement and concrete to improve strength, durability, and resistance to corrosion. It is also used in the production of wallboards, floor tiles, and other construction products.

Agriculture: Used as a magnesium fertilizer to correct magnesium deficiency in crops, promoting growth and improving yield and quality. It is suitable for various soils and crops such as fruits, vegetables, and grains.

Pharmaceuticals & Food: Used as an antacid and laxative in pharmaceuticals. In the food industry, it acts as a food additive (E530) for pH adjustment, thickening, and anti-caking.

FAQ

Q1: What is the difference between different forms of Magnesium Oxide (powder, granular, flake, prill)?

A1: The main difference lies in particle size and shape, which determine their application scenarios. Powder form has fine particles, suitable for industries requiring high reactivity such as chemicals and pharmaceuticals. Granular and prill forms have larger particles, good fluidity, and are easy to transport and apply, suitable for agriculture and building materials. Flake form has a sheet-like structure, suitable for refractory materials and some special chemical processes.

Q2: Is Magnesium Oxide with CAS 1309-48-4 compliant with international standards?

A2: Yes, Magnesium Oxide with CAS 1309-48-4 meets international standards such as REACH (EU), FDA (US), and GB (China). It has passed REACH registration, and MSDS download is available to provide detailed safety and compliance information for users.

Q3: How to store Magnesium Oxide properly?

A3: Magnesium Oxide should be stored in a dry, well-ventilated warehouse, away from moisture, acids, and other incompatible substances. It should be sealed to prevent absorption of water and carbon dioxide from the air, which may affect its performance. During storage, avoid heavy pressure and collision to prevent packaging damage.
