Molybdenum Heating Zone for Vacuum Furnaces
Molybdenum Hot Zone Assembly for Vacuum Heat Treatment Furnaces
Our Molybdenum Hot Zone Assembly is engineered for high-temperature vacuum furnaces, delivering excellent thermal stability, low vapor pressure, and long service life.
Designed for demanding applications such as vacuum heat treatment, semiconductor processing, and crystal growth, this hot zone ensures consistent temperature uniformity and reliable performance under extreme conditions.
Product Overview
The Molybdenum Hot Zone Assembly is a critical internal component of vacuum furnaces, responsible for thermal insulation, heat containment, and structural stability at temperatures exceeding 1600–2200°C.
Manufactured from high-purity molybdenum and precision-fabricated using advanced forming and Electron Beam Welding (EBW) processes, our hot zones are optimized for high vacuum environments, minimizing contamination while maximizing operational lifespan.
This product is suitable for both new furnace systems and replacement or upgrade of existing hot zones, helping customers improve furnace efficiency and reduce total operating costs.
