Vulcan Semiconductor Diffusion Heater
High-temperature diffusion furnace heater, to 1,350°C
The Vulcan is DS Fibertech’s high-temperature diffusion furnace heater, rated to 1,350°C. It uses large-gauge Kanthal APM element wire, held by high-strength interlocking ceramic separators, with built-in reinforcements that stop the element sagging where one heating zone meets the next. The end vestibules are made to resist cracking and shrinking under stress.
Construction
DS Fibertech’s cross-section, from the process tube outwards: a 1,800°C alumina coating on the hot face, which stops the fibre shedding dust; alumina interlocking spacers and the helical element, set in DS Fibertech’s own vacuum-formed ceramic fibre; cold-face layers and an insulation blanket; and a stainless steel shell, with Kanthal leads passing through lead isolators.
Specifications
- Rated to 1,350°C
- Element wire: Kanthal APM
- Insulation: vacuum-formed ceramic fibre
- Hot-face coating: alumina, rated to 1,800°C
- Built for horizontal or vertical furnaces, to the OEM part number or a drawing
Choosing a design
The Vulcan is for furnaces run at the top of the temperature range. The Hercules is the high-temperature design in Kanthal A1, to 1,300°C. For fast ramp and cool, see the Mercury; for low-temperature work, the Apollo. If you’re replacing an element in an existing furnace, start with the OEM part number on the replacement elements page.
