Molybdenum heating elements, particularly molybdenum disilicide (MoSi2), are versatile components used across various high-temperature industrial applications. Their ability to withstand extreme temperatures (up to 1850°C) and maintain stable resistance makes them ideal for processes like glass manufacturing, ceramic sintering, and semiconductor fabrication. Available in multiple configurations (wire, rod, strip, tubes), they offer durability, fast thermal cycling, and compatibility with vacuum furnaces for brazing or hardening. Their unique properties, such as the ability to connect old and new elements in series, make them a preferred choice for demanding thermal environments.
Key Points Explained:
-
High-Temperature Performance
