- Some tube furnaces have an intregral ceramic worktube, others require one to be added to operate
- All tube furnaces require an additional ceramic or inconel worktube to allow the use of a gas atmosphere
- Various worktubes are available to suit different applications
- Sillimanite - porous, good thermal shock resistance, maximum temperature 1500°C
- Impervious aluminous porcelain (IAP) - impervious, maximum temperature 1400°C
- Mullite - impervious and resistant to flux, sulphurous & carbonaceous atmospheres, maximum temperature 1500°C
- Recrystallised alumina (RCA) - impervious and highly resistant to chemical attack (99.7% Al2o3), maximum temperature 1800°C
- Advanced powder metallurgy (APM) - impervious FeCrAl alloy tube, not susceptible to thermal shock, but unsuitable for use inside (MTF & CTF) wire wound tube furnaces, maximum temperature 1300°C
