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.
