Magnesium Nanopowder (Mg, 99%, 800 nm) is a high-purity material composed of magnesium nanoparticles with a particle size of 800 nanometers (nm) and a purity level of 99%. This nanopowder retains many of the unique properties of magnesium, such as light weight, high reactivity, and excellent thermal properties, but at the nanoscale, it exhibits enhanced characteristics like increased surface area and reactivity. This makes it suitable for a variety of advanced applications in industries such as aerospace, energy storage, and metallurgy. Below is a detailed overview of the key features, properties, and applications of magnesium nanopowder.
Key Features:
Magnesium (Mg):
Magnesium is a lightweight, highly reactive metal known for its low density and high strength-to-weight ratio. When reduced to nanopowder form, its reactivity increases, making it useful in applications requiring high surface area and chemical reactivity. Magnesium nanopowder also retains the inherent properties of bulk magnesium, such as excellent thermal conductivity and corrosion resistance.
Purity (99%):
The 99% purity ensures that the magnesium nanopowder has minimal impurities, providing consistent and reliable performance across various applications. High purity is particularly important in scientific and industrial processes where material quality is crucial.
Particle Size (800 nm):
The 800 nm particle size offers a balance between increased surface area for enhanced reactivity and the physical stability required for industrial handling. The moderate size ensures ease of dispersion while maintaining the material’s effective properties for various applications.
Properties:
Lightweight:
Magnesium is one of the lightest structural metals, with a density of about 1.738 g/cm³. The nanopowder form preserves this characteristic, making it ideal for applications that require lightweight materials, such as aerospace, automotive, and military applications where weight reduction is critical.
High Surface Area and Reactivity:
Magnesium nanopowder has an increased surface area compared to bulk magnesium, enhancing its reactivity. This makes it highly effective in catalytic processes, energy storage, and chemical reactions. The increased surface area allows for faster chemical interactions and more efficient utilization of the material.

The powder can help improve heat dissipation in high-performance electronics. - Composite Materials:
Magnesium nanopowder is used in the creation of advanced composite materials that require a combination of lightness, strength, and high thermal conductivity. These composites can be applied in high-performance applications, such as in sports equipment, aircraft, and protective gear. - Environmental Remediation:
Due to its high reactivity, magnesium nanopowder can be used in environmental remediation processes, such as water treatment and soil decontamination. It is particularly effective in removing heavy metals and other pollutants from wastewater and soil.
Handling and Safety:
Health and Safety Considerations:
Magnesium nanopowder should be handled with care to avoid inhalation, ingestion, or skin contact. Magnesium dust is flammable and can pose fire hazards, so it is important to follow appropriate safety protocols, including using personal protective equipment (PPE) such as gloves, masks, and safety goggles.
Storage:
Store magnesium nanopowder in a cool, dry, and well-ventilated area to prevent the powder from coming into contact with moisture or air, which can lead to oxidation. The material should be kept in tightly sealed containers to avoid contamination and degradation of its properties.
Precautions:
When handling magnesium nanopowder, avoid generating dust or aerosols, as they can be easily ignited. Use proper ventilation and fire suppression measures in the workspace. Dispose of the material in accordance with local regulations to avoid environmental contamination.
Summary:
Magnesium Nanopowder (Mg, 99%, 800 nm) is a highly reactive and versatile material with a range of advanced properties. Its lightweight nature, high surface area, and reactivity make it ideal for a wide array of applications, including aerospace, energy storage, catalysis, and biomedical uses. The material’s moderate particle size (800 nm) offers a balance of surface area and stability, making it suitable for a variety of industrial and scientific processes. Proper handling and safety precautions are crucial for ensuring the safe use of magnesium nanopowder in high-performance applications.
