Pure magnesium powder is a kind of metal powder made of high purity magnesium, which has the characteristics of light weight, high activity and unique chemical properties. Due to its unique physical and chemical properties, pure magnesium powder has a wide range of applications in many fields such as chemistry, metallurgy, military, aerospace and so on. It is usually made into fine powder by mechanical processing or atomisation of pure magnesium block system, and the particle size can be controlled according to the demand.
Pure magnesium powder characteristics
1. Lightweight: magnesium is one of the lightest metal structural materials, with a density of 1.74 g/cm³, which makes magnesium powder have a low density and is suitable for the field of lightweight material demand.
2. High activity: magnesium powder has high chemical activity, especially in the air is easy to with oxygen in a violent oxidation reaction, release a lot of heat energy. Therefore, magnesium powder is extremely easy to burn under high temperature and strong oxidising environment.
3. Flammability: Pure magnesium powder is extremely easy to ignite and the combustion temperature is very high, combustion in the air will produce dazzling white light, so in the storage and use of the process need to pay special attention to fire prevention and to prevent contact with oxygen.
4. Good electrical and thermal conductivity: magnesium powder has good electrical and thermal conductivity, and can be used to make electrical and thermal conductive materials.
5. Low melting point: magnesium has a low melting point (about 650°C), which makes it uniquely advantageous in some metallurgical fields for easy melting and casting.
pure magnesium powder application
1. Metallurgical industry:
- Reducing agent: Pure magnesium powder is often used as a reducing agent in the metallurgical industry, especially in smelting for the production of certain rare metals such as titanium, zirconium and uranium. Magnesium can react with certain metal oxides to produce pure metals.
- Desulphurising and deoxidising agent: magnesium powder is widely used in steel production as a desulphurising and deoxidising agent, capable of removing sulphur and oxygen from steel and improving the quality and purity of steel.
2. Chemical industry:
- Chemical reaction: magnesium powder is used as a strong reducing agent in many chemical reactions. It is often used in organic synthesis and preparation of metal compounds.
- Preparation of catalysts: Magnesium powder can also be used as a raw material for certain catalysts, which are widely used in the production of chemical products.
3. Military and aerospace field:
- Pyrotechnics and Explosives: due to the high combustibility and strong light effect of pure magnesium powder, it is used as a component of pyrotechnics, flashbangs, flares, smoke-emitting agents and explosives. Magnesium powder is widely used for military purposes because of its high combustion temperature and its ability to produce extremely bright light.
- Solid rocket propellant: Magnesium powder is sometimes used as an additive to rocket fuel to enhance combustion efficiency and energy release.
4. Alloy Materials: Pure magnesium powder can be used as a raw material for the manufacture of magnesium-based alloys, which are widely used in automobiles, aerospace, and electronic products, and have the advantages of light weight and high strength.
5. Electronics industry: In the electronics industry, magnesium powder is used in the manufacture of certain high-performance electronic materials, such as energy storage materials and conductive materials.
6. MEDICAL FIELD: Because magnesium is biocompatible, pure magnesium powder is used in the development of certain medical devices, such as biodegradable metal implants and drug carriers.
