Essential Technical Properties and Trade Terminology for 硅 粉

Key Technical Properties of 硅 粉 (Silicon Powder)

When sourcing 硅 粉 for industrial or manufacturing purposes, understanding its technical specifications is crucial for ensuring product quality and compatibility with your applications. Below are the primary properties you should evaluate:

• Purity (%)
  This indicates the percentage of silicon content in the powder. Higher purity (typically above 99%) is essential for applications such as electronics, solar panels, and high-performance alloys. Lower purity grades may be suitable for less critical uses like metallurgical additives. Purity directly impacts the efficiency and reliability of your end product.

• Particle Size (Microns)
  Particle size distribution affects the surface area and reactivity of the powder. Finer particles (below 10 microns) offer better dispersion and reactivity, which is vital in chemical processes or coatings. Coarser powders may be preferred for bulk materials or certain metallurgical processes. Consistent particle size ensures uniformity in production.

• Specific Surface Area (m²/g)
  This measures the total surface area per gram of powder, influencing chemical activity and bonding characteristics. A higher specific surface area enhances reaction rates and sintering behavior, important for advanced material manufacturing. It also affects flowability and packing density.

• Moisture Content (%)
  Silicon powder should have low moisture content to prevent clumping and degradation. Moisture can adversely affect storage, handling, and chemical reactions. Typically, moisture below 0.5% is recommended for industrial-grade powders.

• Bulk Density (g/cm³)
  Bulk density impacts packaging, transportation, and mixing ratios in formulations. Knowing this helps in calculating volume requirements and optimizing logistics costs. Variations can affect dosing accuracy in production.

• Crystallinity and Phase Composition
  Silicon powder may be amorphous or crystalline. Crystalline silicon is preferred in electronics and photovoltaics, while amorphous silicon finds use in coatings and chemical applications. Confirming phase composition ensures the powder meets your process needs.

Common Trade Terminology for International B2B Transactions

Navigating international procurement and trade contracts for 硅 粉 involves understanding key industry jargon. Below are terms frequently encountered in supplier negotiations and contracts:
