Q: Why refractory metals are used in the high temperature furnaces?

A: Refractory metals such as tungsten, molybdenum are ideal for high temperature furnaces due to their outstanding properties:
• Temperature up to 2800°C in vacuum or protective atmospheres
• Low vapor pressure
• Low thermal expansion
• High mechanical and thermal stability
• Excellent uniformity
