1. Materials and characteristics of graphite heating elements
The main material of graphite heating elements is graphite, which is a non-metallic element with a series of excellent physical and chemical properties.
High temperature resistance: Graphite can maintain stable physical and chemical properties in high temperature environment, usually working at a high temperature of 2000℃, and its strength increases with the increase of temperature.
Electrical conductivity: Graphite has very good electrical conductivity, which is 100 times higher than that of general non-metallic minerals. It can quickly convert electrical energy into thermal energy to achieve efficient heating.
Thermal conductivity: The thermal conductivity of graphite is also very outstanding. Its thermal conductivity exceeds that of metal materials such as steel, iron, and lead, which can ensure the uniformity of heating.
Corrosion resistance: Graphite is resistant to corrosion to most chemicals and can remain stable in harsh chemical environments.
Environmental protection: Graphite is an environmentally friendly material that does not produce harmful gases or radiation and is harmless to the environment and human health.
2. Application fields of graphite heating elements
Due to their excellent performance, graphite heating elements are widely used in various occasions requiring high-temperature heating:
Semiconductor manufacturing: In the semiconductor manufacturing process, graphite heating elements are widely used in heat treatment processes such as diffusion, annealing, welding and other links. In addition, they can also be used in the testing and verification process of semiconductor equipment to ensure the stability and reliability of the equipment.
Vacuum furnace: Graphite heating elements are widely used in vacuum furnaces and can be used in single crystal pulling, metal smelting and other processes. Its high temperature resistance, corrosion resistance, high thermal conductivity and other characteristics make it an ideal heating element in a vacuum furnace.
Industrial furnace: Graphite heating elements can also be used in the heating systems of various industrial furnaces, such as melting furnaces, ceramic furnaces, etc. In these occasions, graphite heating elements can ensure stable and uniform heating at high temperatures.
