High-Frequency Induction Heater

The high frequency induction heating system MU-α series is made compact in a personal-computer size into which a conventional large-sized and expensive heating system is being transformed. This space-saving and highly functional system MU-α is to be used for study of physical properties, study of semiconductors, and sample preparation.

Highest Attainable Temperature

When using a crucible made of a material having a high melting point such as carbon, tungsten, or molybdenum, operations can be executed at a maximum temperature of about 2,200°C.

(Ex.) Heating carbon in a vacuum using carbon fiber as a thermally insulating light blocking material



  • Rapid heating
  • When a metallic specimen, for example, 30 g of a Co-Cr alloy, is directly heated, it can be heated to 1,400°C(melting point) in about 20 sec.
  • Rapid cooling
  • The crucible and the oven core tube made of inorganic materials are not heated, resulting in rapid cooling.
  • When the oven core tube is made of quartz, the inside can be observed.
  • When a carbon crucible is used, inorganic specimens can be heated indirectly.
  • Only necessary portions can be heated.
  • If composite specimens made of metal and ceramic or plastic, only the metal portion can be heated.
  • Simple easy-to-maintain structure.
  • As an example application, this heater can be incorporated in a glove box to heat, melt and calcine specimens in inert gas.

    Heating of specimens under vacuum in a quartz tube

  • Heating of Fluids

    Heating of Fluids

    Heating of liquids, powders or gases by placing a heater (carbon honeycomb, metallic ring or the like) in the fluid passage.

  • Encapsulation of Electrodes

    Encapsulation of Electrodes

    A glass specimen is locally heated,molten,and welded to the electrode such that the inside gas is encapsulated.

  • Hardening and Annealing

    Hardening and Annealing

    Heating of specimens, for example, a SUS round rod of 20φ, to 600°C in about 30 sec.

  • Direct Heating

    Direct Heating

    Direct heating of metallic specimens. One of a variety of crucibles is to be selected according to heat resistance and reactivity.

  • Evacuation (Gas Replacement)

    Evacuation (Gas Replacement)

    With the use of a vacuum/gas replacement unit (optional), just the atmosphere around specimens can be controlled.

  • Indirect Heating

    Indirect Heating

    Heating and melting pure silicon, glass, ash, or other specimens by high-frequency induction rather than direct heating.

  • In a Vacuum/Pressurized Container

    In a Vacuum/Pressurized Container

    Study of battery materials or preparation of alloys from metals of differing melting or boiling points.
