Component Specifications

Definition
Silicon (Si) is a metalloid element with atomic number 14, serving as the primary silicon source in high-purity molybdenum disilicide (MoSi2) powder manufacturing. In this context, silicon is processed to achieve purity levels exceeding 99.9% and combined with molybdenum through powder metallurgy techniques to create MoSi2, which exhibits exceptional oxidation resistance and stability at temperatures up to 1700°C.
Working Principle
Silicon atoms bond with molybdenum atoms in a 2:1 stoichiometric ratio to form molybdenum disilicide (MoSi2) through high-temperature synthesis. The silicon provides the necessary silicon content for creating the protective silica (SiO2) layer that forms on MoSi2 surfaces at elevated temperatures, enabling its use as heating elements in industrial furnaces.
Materials
High-purity silicon (≥99.9% Si) with controlled particle size distribution (typically 1-10 μm), low oxygen content (<0.1%), and minimal metallic impurities (Fe, Al, Ca < 100 ppm each).
Technical Parameters
  • Purity ≥99.9%
  • Bulk Density 0.8-1.2 g/cm³
  • Particle Size 1-10 μm
  • Oxygen Content <0.1%
  • Metallic Impurities <100 ppm each
  • Specific Surface Area 2-5 m²/g
Standards
ISO 4497, ASTM B214, DIN 66165
