Dilated graphite powder is a loose and porous worm like substance made from natural flake graphite, hence also known as graphite worm. Natural flake graphite is a crystal with a layered structure, where carbon atoms in each layer form a network of planar macromolecules through strong covalent bonds, and the layers are weakly bonded by van der Waals forces. Under the action of strong oxidants, the network of planar macromolecules become positively charged planar macromolecules, causing polar sulfate molecules and negative ions such as hydrogen sulfate ions to insert into the graphite layer and form expandable graphite powder, also known as graphite intercalation compound (GIC). Due to the formation of a unique network pore system during the puffing process, with a large specific surface area and high activity of the resulting fresh surface, it has excellent adsorption performance and other special properties, and has a wide range of applications.

Graphite plates are an important industrial material with good electrical conductivity, high temperature resistance, acid and alkali corrosion resistance and easy processing. The following are the main uses of graphite plates:

The design and production of low-power graphite electrodes mainly focus on optimizing their conductivity, heat resistance, mechanical strength, and reducing energy consumption to meet the demand for low energy consumption and high efficiency in specific industrial applications such as electric arc furnace steelmaking and resistance furnace heating.

As a commonly used smelting tool, graphite crucible is widely used in metal smelting, alloy preparation, chemical reaction and other fields.

Low power graphite electrodes are specifically designed for use in electric furnaces or electrolytic processes at lower current densities and lower operating temperatures. These electrodes need to have good electrical conductivity, mechanical strength, thermal shock resistance, and some corrosion resistance, and in order to reduce energy consumption and cost, they need to have an optimized structure to reduce unnecessary power loss. Below are some points and recommendations that can be considered when designing low power graphite electrodes:

According to the different raw materials used and the differences in physical and chemical indicators of the finished products, graphite electrodes are divided into three varieties: ordinary power graphite electrodes (RP grade), high-power graphite electrodes (HP grade), and ultra-high power graphite electrodes (UHP grade).
