Component Specifications

Definition
Molybdenum (Mo) is a transition metal with atomic number 42, characterized by high melting point (2623°C), excellent thermal conductivity, and corrosion resistance. In industrial applications, it serves as a critical component in high-purity molybdenum disilicide powder production for heating elements, where it provides structural stability and electrical conductivity at extreme temperatures exceeding 1700°C.
Working Principle
Molybdenum functions as the metallic base in molybdenum disilicide composites, where its crystalline structure provides electron mobility for electrical heating while maintaining mechanical integrity through strong metallic bonds that resist deformation at high temperatures.
Materials
Pure molybdenum (99.95% min), typically produced via powder metallurgy or arc-casting processes, with trace elements controlled to <500ppm for high-temperature stability.
Technical Parameters
  • Density 10.28 g/cm³
  • Purity Grade ≥99.95%
  • Atomic Number 42
  • Melting Point 2623°C
  • Crystal Structure Body-centered cubic
  • Thermal Conductivity 138 W/m·K
  • Electrical Resistivity 5.34 μΩ·cm
Standards
ISO 12163, ASTM B387, DIN 17465
