High Temperature Furnace Applications

These high temperature vacuum and argon atmosphere furnaces utilize Molybdenum and Tungsten materials produced by H.C. Starck.

Lab Testing Furnaces

  • High temperature capabilities in vacuum, reducing or inert atmospheres
  • Chemical reactions furnaces (vacuum, air, or different atmospheres)
  • H.C. Starck provides services for pre-characterization of materials for customers, for example, performance of material  after high temperature anneal

Controlled Atmospheres Furnaces Application

  • Aerospace
    Rocket nozzles
  • Medical
    Orthopedic and joint replacements
  • Energy
    Carbide drilling equipment

    Heating elements and heat shields

Sapphire Crystal growth furnaces have uniquely designed hot zones for accommodating crucibles that melt alumina for high quality substrates applied in LED manufacturing.

Molybdenum Sheet, Plate and Foil

Products H.C. Starck produces a wide range of molybdenum and molybdenum alloy mill products using two primary consolidation methods; vacuum arc-casting (AC) and powder metallurgy (PM). The availability of products from both of these established processes gives users many options in selecting a material to satisfy their specific application requirements. Mill products available from either process include forging billets, bar, rod, sheet, plate and foil.
