The advantages of graphite heating elements in vacuum environments are mainly reflected in the following aspects:
1. Good thermal performance
High temperature stability: Graphite materials can maintain stable performance at high temperatures and are not easily melted or deformed, which enables graphite heating elements to work continuously and stably in high-temperature vacuum environments.
Thermal conductivity: Graphite has good thermal conductivity, which can quickly transfer heat to the heated object and improve heating efficiency. In a vacuum environment, due to the absence of convection and thermal losses, the thermal conductivity of graphite can be better utilized.
2. Chemical stability
Corrosion resistance: Graphite exhibits better chemical stability in a vacuum environment and is less prone to chemical reactions with the protective atmosphere, lining, and supports inside the furnace. This enables graphite heating elements to be used for a long time in various corrosive environments, extending the service life of the equipment.
Antioxidant: Under vacuum or inert atmosphere, graphite is not easily oxidized, thus avoiding performance degradation and damage caused by oxidation.
3. Mechanical properties
Low coefficient of expansion: The thermal expansion coefficient of graphite is relatively small, which means that during the heating process, the size change of graphite heating elements is small, which is conducive to maintaining the stability and accuracy of the equipment.
Good mechanical strength: Although graphite has lower hardness at room temperature, it can still maintain a certain mechanical strength at high temperatures and withstand certain mechanical stress and vibration.

4. Processing performance
Good processability: Graphite material is easy to process into various shapes and sizes, which allows graphite heating elements to be customized and designed according to specific needs.
5. Environmental protection and energy conservation
Pollution free: Graphite heating elements do not produce harmful gases or substances during the heating process, and are environmentally friendly.
Energy saving: Due to the good thermal conductivity and low coefficient of thermal expansion of graphite, graphite heating elements can reduce heat loss and improve energy utilization efficiency during the heating process.
6. Widely applicable fields
Graphite heating elements can effectively avoid oxidation and decarburization phenomena and improve the performance and quality of metal materials during heat treatment (such as annealing, normalizing, tempering, etc.) in a vacuum environment.
Graphite heating elements can provide stable high-temperature environments in various fields such as ceramic material sintering, electronic material preparation, chemical vapor deposition (CVD), high-temperature alloy melting, pyrolysis and carbonization, and scientific research experiments, meeting various process requirements.
