Metalmaster - A vacuum furnace with a refractory metal hot zone

METALMASTER - A Vacuum Furnace With A Refractory Metal Hot Zone

Metalmaster furnaces are designed for processing of refractory metals under high vacuum conditions at elevated temperatures. They can be supplied without high vacuum pumps for processing under inert or reducing gas atmospheres. In addition to refractory metal processing, Metalmaster furnaces are also used for processing high purity advanced ceramic materials which are susceptible to contamination in traditional graphite furnaces.

Each vacuum furnace is supplied as a complete system including: vacuum chamber; metallic heat zone; power supply; vacuum pumps; and a programmable control system. Optional upgrades to the power supply, vacuum pumps, and controls are available to meet individual requirements.

Metalmaster

Each Metalmaster vacuum furnace is fabricated with a stainless steel chamber, water jacket, and flanges. Internal baffling efficiently directs water flow, permitting heat zone operation to 2500°C without use of an intermediate water-cooled copper "heater shell."

Cylindrical mesh heating elements provide uniform heating from 360° while operating at a low watt density for long life. Multiple radiation shields conserve energy while providing a clean environment and rapid thermal cycling capability. Heat zones are designed for prolonged use at normal operating temperatures and intermittent use at maximum operating temperatures.

Tungsten	Tungsten & Molybdenum	2500 2200
Tantalum	Tantalum	2500 2200
Molybdenum	Molybdenum & Stainless Steel	1700 1600
