Furnace Range for Graphitisation at Temperatures
kejia offers a range of furnaces up to 1700 °C which are perfectly suitable for the various requirements of graphitization. Heat treatment up to 1700 °C under inert atmosphere induces the structural change from highly disordered or defective carbon atom structures into a perfectly three-dimensional crystal of pure graphite, an important material for a multitude of applications.
For starting material which consists solely of carbon atoms and is very clean with minor impurities, a graphite furnace of the LHTG range or the HTK range up to 3000 °C is suitable. Both, heating elements and insulation of the cold wall furnaces consist of high quality graphite materials. The top loader furnace LHTG is fitted with a circular mantle heater in a perfectly symmetrical meander.
If organic matter of unknown composition, or containing a large amount of impurities is used for graphitisation, it is recommended to purify the sample by pre-carbonisation under inert gas atmosphere before heat treatment in a more sensitive high temperature graphite furnace. This can be done in a low temperature hot wall furnace of the GLO range up to 1100 °C.
kejia offers specialized HTK graphite furnaces with dedicated debinding equipment, where carbonisation and graphitisation are carried out in one heat treatment step. Those furnaces are equipped with a retort and an intelligent gas guidance system which assures that the impurities are safely discharged from the furnace into the afterburner.
