STF CTF High Temperature Tube Furnaces

The 1500°C and 1600°C tube furnace ranges utilise silicon carbide heating elements arranged in a heated chamber surrounding the work tube, and provide even heating of the tube surface for maximum temperature uniformity. SiC furnaces can be used either horizontally or vertically and are offered with two heated lengths and two temperature ranges.

1700°C tube furnaces use molybdenum disilicide (MoSi₂) heating elements suspended down each side of a horizontal tube. At elevated temperatures these heating elements become very soft and therefore the standard furnace is only suitable for horizontal use. Custom built vertical furnaces are available on request.

Vertical Tube Furnace

1800°C tube furnaces (type PVT) use lanthanum chromite heating elements, which generally achieve slower heating rates. These furnaces are for use in the vertical position only , and the elements are suspended around a vertical tube. Again, special custom built tube furnaces at 1800°C are available. Although the elements give off a small amount of chromium vapour the work tube shields all but the most sensitive work pieces from contamination or pink colouration.
