Overview of China competitive silicon metal 99.9% powder

China competitive silicon metal 99.9% powder comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.

Key Characteristics of China competitive silicon metal 99.9% powder

  1. Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.

  2. Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.

  3. Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.

  4. Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of China competitive silicon metal 99.9% powder

Silicon metal, specifically 99.9% purity, is a high-quality form of elemental silicon used in various industries due to its exceptional properties. Here are some key parameters for this type of silicon metal powder:

1. Purity: 99.9% – This indicates that the silicon metal contains less than 0.1% impurities, making it extremely pure and suitable for applications requiring high levels of integrity.

2. Particle size distribution: The particle size can vary depending on the specific manufacturing process, but generally, it’s available in different grades like sub-micron, micron, or a combination (e.g., 40-75 mesh or 90+% passing through a specified sieve). It’s essential to specify the desired particle size when ordering.

3. Crystal structure: Silicon metal typically exists in a metallic form with a face-centered cubic (FCC) crystal structure.

4. Melting point: Silicon metal has a melting point of approximately 1,414°C (2,583°F).

5. Density: Silicon metal has a density of around 2.33 g/cm³.

6. Electrical conductivity: As a semiconductor, silicon metal has good electrical conductivity but lower than metals like copper or aluminum.

7. Chemical resistance: High-purity silicon metal is resistant to corrosion in many environments, but it can react with strong acids and alkalis.

8. Thermal conductivity: Silicon metal has good thermal conductivity, which makes it useful in heat transfer applications.

9. Oxidation behavior: In air, silicon metal will slowly oxidize, forming a thin layer of SiO2 (silicon dioxide), which can protect the metal from further corrosion.

10. Storage and handling: It’s important to store silicon metal in an airtight container away from moisture and oxygen to maintain its purity.

These parameters may vary slightly depending on the supplier, so it’s always best to consult the manufacturer’s specifications for the most accurate information.
