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.

Titanium dioxide, with the chemical formula TiO2, has stable physical and chemical properties and excellent optical properties and photochemical activity, so it is widely used in coatings, plastics, rubber, chemical fibers, papermaking, inks and so on.

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

More and more customers, while using traditional copper electrodes for EDM, are beginning to realize some new trends of technological change: “How can we apply limited resources to increase production value, and how can we save time, cost and energy in the same situation?” Graphite electrode as EDM electrode material, with its high cutting, light weight, fast forming, very small expansion rate, small loss, easy to repair and other advantages, is due to its special stable physical properties and gradually become the future trend of EDM electrode material, has been widely used in the mold industry, instead of copper electrode has become inevitable.

Graphite anode plates are used in industries such as electrolytic calcium production and electrolytic magnesium production. It is characterized by low resistivity, high volume density, good bending and erosion resistance, and long service life.

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).
