Purification Fce

Carbon Purification Furnace

This is an ultra-high temperature vacuum furnace in which a muffle is installed inside a horizontal or vertical graphite hot zone. Samples of carbon-based materials or parts such as bulk, fiber, and powder are loaded into the muffle and heated to 2,300°C or higher under vacuum or partial pressure control conditions while flowing chlorine or fluorine-based halogen gas. Thereby, by removing impurities in the form of chloride or fluoride, samples shall be highly purified.

Features - DC Power supply optional

  • Closed electrode structure featuring minimal radiant

    heat loss and the suppression
    of electric discharge

  • Triple protection of the dry
    pump by inlet filtration,
    pump’s self-cleaning and pro-
    hibition of exhaust back flow

  • Life extension of hot zone
    through separate control of
    pressures between Cl2
    gas
    and N2 protective gas

  • Securing accuracy of temp.
    control through optimal
    shift
    of the thermocouple
    and
    the pyrometer

  • Triple surveillance devices of
    power or temperatures to
    prevent overheating accident
    of ultra high temp. furnaces

  • Design of heating load

    securing prevention of

    electric discharge as well as

    life extension

  • Horizontal type or vertical

    type all available depending

    on product shape or loading
    conditions

  • Linked opening and closing

    of the muffle and the

    chamber door assuring
    easy sample loading
