Molybdenum vacuum heating furnace zone
Molybdenum Vacuum Heating Furnace Zone Solutions
Core Advantages
✅ Extreme Temperature Resistance - Manufactured from high-purity molybdenum/TZM alloys, withstanding continuous operation at 1800°C (peak 2200°C)
✅ Uniform Thermal Field - Multi-layer molybdenum heat shields ensure ±3°C temperature uniformity
✅ Extended Lifespan - Special surface treatment extends service life 3-5x vs conventional materials
✅ Ultra-High Vacuum Compatibility - Low outgassing rate (<5×10⁻⁶ Torr·L/s), suitable for 10⁻⁶ Pa UHV systems
