Graphitization furnace is a high-temperature furnace that is usually used in high-temperature experiments, chemical reactions, material processing and other fields. Its name comes from the graphite material used inside, which is able to withstand extremely high temperatures and has excellent heat conduction properties. The operating principle of the graphitization furnace is to heat the sample or reactant by heating the graphite element to increase the internal temperature.
Graphitization furnaces usually have precise temperature control that can be adjusted from a few hundred degrees Celsius to thousands of degrees Celsius. This makes it widely used in materials research, catalyst preparation, chemical vapor deposition (CVD) and other fields. Its high-temperature environment also makes graphitization furnaces play a key role in the synthesis of carbon materials such as carbon nanotubes and graphene.
Excellent properties of graphite materials: The graphite components inside the graphitization furnace have excellent thermal conductivity and high temperature resistance. This enables the graphitization furnace to heat samples or reactants quickly and uniformly, and maintain stable operation in high-temperature environments.
Diversity of application fields: Graphitization furnaces are widely used in many fields, including but not limited to materials science, chemistry, physics and engineering. In the field of materials science, graphitization furnaces are often used to synthesize new materials, study material properties, and conduct material processing experiments.
