Carbon nanotubes - high temperature furnaces for production

Carbon nanotubes. The structural changes to create DWNTs and MWNTs occur at a temperature between 2000°C and 2800°C in an Argon atmosphere. The graphite based LHTG laboratory vacuum furnace enables temperatures up to 3000°C and is ideal for this task if carbon is acceptable in the atmosphere.

Carbon nanotube wires for high-temperature performance

As one can see, such a high temperature causes considerable light emission from the CNT films (Fig. 12d) in the visible range in addition to the infrared counterpart responsible for the heating as the temperature is much higher than in similar electrothermal materials based on nanocarbon, . Lastly, we ramped the temperature up to 800 °C and the behavior of the material resembled that of the bare CNT film heaters at 500 °C.
