Experimental Graphitization Furnace Product Description

This series of graphitization furnaces utilizes electromagnetic induction heating to directly heat the graphite crucible, offering high thermal efficiency and energy savings. The experimental graphitization furnace is a custom-made small laboratory model specifically designed for universities, research institutions, and similar entities.

Laboratory Graphitization Furnace Application:

Inductive heating experimental graphitization furnaces are used for sintering, graphitization, and sintering of carbon fiber ropes, as well as the graphitization of carbon fiber filaments and other materials suitable for sintering in a carbon environment. They feature high heating efficiency, ease of operation, and are suitable for industries such as experiments, scientific research, and teaching demonstrations.
For use in ultra-high temperature furnaces up to 3000°C, suitable for various high thermal conductivity graphite films (PI films), lithium battery anode materials, carbon material carbonization and graphitization production of carbon materials, graphitization; graphitized shaping of carbon fiber filaments and other materials that can be sintered in a carbon environment.
