Vacuum Furnaces - Overview

GERO Vacuum Furnaces
for Complex Heat Treatment Processes

Vacuum furnaces for production, laboratory and research:

  • Vacuum pyrolysis furnaces
  • Vacuum sinter furnaces
  • Vacuum siliconization furnaces
  • Vacuum graphitization furnaces
  • Vacuum annealing furnace
  • High vacuum soldering furnace

Vacuum chamber furnaces (up to 2200 °C):

  • Graphite furnaces: employed under vacuum/high vacuum, protective gases (nitrogen / argon), reaction gases (hydrogen / carbon monoxide).
    Example of use: technical ceramics such as SIC, SIN, BC, ALN and combinations. In the field of composite materials the applications are employed for pyrolysis, sintering, siliconizing and graphiting.
  • Metallic furnaces: for greatest possible purity of the process atmospheres or the best possible final vacuum.
    Example of use: lighting industry, metal powder injection moulding, tempering of saphirs, heat treatment of metals, sintering of pellets in the nuclear industry, manufacture of radar tubes, metallisation of ceramic components, high vacuum brazing.
  • Ceramic fibre insulated furnaces: employed for processes with defined oxygen percentages or 100% oxygen atmosphere.
    Example of use: processes for piezoceramic materials, sintering of oxide materials, heat treatments of metals, crystal growing and the manufacture of ceramic powders.

Vacuum hood furnaces (up to 2200°C, optional more)

  • Metallic furnaces without fibre insulation: for generating the lowest achievable operation pressures in vacuum operation and the best quality of high purity gas atmospheres. Lowest vapour pressure / highest temperatures. High vacuum operation up to 10-7 mbar. Nitrogen, Argon, Hydrogen or mixtures
    Example of use:     rapid prototyping, MIM, cristal growth, degassing, brazing.

Vakuum bottom loader (up to 2200°C)

  • Graphite furnaces: employed under vacuum / high vacuum, protective gases (nitrogen / argon), reaction gases (hydrogen / carbon monoxide).
    Example of use: technical ceramics (SIC, SIN, BC, ALN and combinations). In the field of composite materials the applications are employed for pyrolysis, sintering, siliconizing and graphiting.
  • Metallic furnaces: greatest possible purity of the process atmospheres or the best possible final vacuum.
    Example of use: employed for specimens requiring treatment in carbon-free atmospheres, e.g. in the lighting industry, metal powder injection moulding, tempering of saphirs, heat treatment of metals, sintering of pellets in the nuclear industry, manufacture of radar tubes, metallisation of ceramic components, high vacuum brazing.

Vacuum laboratory furnaces (2200°C up to 3000°C)

Tube furnaces (up to 1800°C)
