Each system is supplied with one furnace of choice.
The choices are; either a 2200 C Carbon furnace,
1450 C Molybdenum furnace,
or 1200 C Kanthal.
All furnaces are easily plugged into the vessel and fully interchangeable.
Therefore you can purchase additional furnaces for use in the system
either initially or later. Hot zones vary slightly with temperature. Many customers
purchase different furnaces for various applications.
Carbon furnaces are used for high temperature ceramics work, and also when
Nitrogen use is of interest.
Carbon furnaces can also be used under vacuum to 1700 C allowing sintering
(binder less only) and low pressure work to be done.
The vacuum level achievable is typically around 100 to 200 microns.
Molybdenum furnaces are very clean and used for ceramics such as
Alumina and Zirconia, as well as most metals.
Molybdenum furnaces can only be used in Argon.
Kanthal furnaces are rugged and can be used for metals and castings.
They can also be operated in up to 20 percent Oxygen therefore allowing use with
superconductors and oxide ceramics that are prone to breakdown.
We also offer units in 45,000 psi (300 Mpa) and 60,000 psi (400 Mpa) versions which
can be advantageous for ceramic and nano-powder work when you need to lower
the temperatures to reduce grain growth.
