Heat shields

Materials: Molybdenum, Tungsten or TZM

Heat shields are produced by fabricating double-walled cylinders from tapered sheet.

The wall cavity is filled with Molybdenum or Molybdenum-Tungsten alloy powder or filings and the assembly is exposed to high temperature thereby rendering it solid.

Such components can be produced using the above technology (with advantages in increased thermal stability and component life) or by riveting of cambered plates, as required. Note: for other types of heat shields, please contact us.

Applications: heat shields work at very high temperatures under hydrogen or vacuum and are widely used in those furnaces where sintering, single-crystal growth, glass melting, synthetic sapphire production, etc, is practised.


Materials: Molybdenum, Tungsten, Tantalum.

Applications: Crucibles are used under vacuum or inert atmosphere for various metal production processes including reduction, refining, distillation, as well as the melting of scandium, yttrium, lutetium, dysprosium and other metals and alloys with melting point at 3000°C. They also are used in synthetic sapphire and ruby production, single-crystal growth, vacuum thermal sputtering of metallic films in furnaces operating above 2000°C.

Heating elements

Materials: Molybdenum, Tungsten and MoW30 alloy.

Applications: vacuum or hydrogen electrical-resistance furnaces, induction furnaces for sintering applications, operating in temperatures above 2000°C for extended periods.

End-use: component sintering, glass melting, single-crystal growth.

Sputtering Targets

Materials: 99.95% Molybdenum, 99.95% Niobium and 99.999% Tantalum billets.

Applications: metal sputtering onto glass surface for very thin metallic film coating ; semi-conductor production.

End-use: optical industry, solar panels, sunray-insulating glass, etc.

Trays and boats

Material: Molybdenum, TZM, Tungsten, Tantalum

Trays are either manufactured from sheet by forming and riveting or from powder by pressing and sintering. The production process guarantees high thermal stability and long working life.

Applications: High temperature heat treatments, under hydrogen or vacuum for component sintering, oxide reduction, glass melting, single-crystal growth, etc.


Material: Molybdenum

Applications: such discs are used for the production of high-power silicon semi-conductor.
