Classification And Use Of Graphite Powder

The main characteristics and characteristics of graphite Introduction of high-temperature resistance The strength of graphite strengthen with increasing temperature. At 2000℃, the power of graphite doubles. The electrical conductivity of thermally conductive graphite powder is one hundred times higher than that of common non-metallic minerals. The thermal conductivity exceeds metal materials such as steel, iron, etc. The thermal conductivity decrease with increasing temperature, and even at extremely high temperatures, graphite becomes an insulator. Lubricity depends on the size of graphite flakes. The larger the chips, the smaller the friction coefficient and the better the lubricating performance. Chemical stability It has excellent chemical stability at room temperature and is resistant to corrosion by acids, alkalis, and organic solvents. It has good plasticity and toughness and can be rolled into a thin sheet. Thermal shock resistance When used at room temperature, it can withstand drastic changes in temperature without damage and sudden changes in temperature.

According to the different scale sizes, scale graphite can be divided into four categories: giant scale graphite, large scale graphite, medium scale graphite and small scale graphite. The crystallization degree of graphite and the size of flakes are different, and the physical and chemical properties and relevant fields are also different. In the past, the larger the flakes, the higher the value of graphite. As the demand for lithium flake anode materials for small flake graphite rises, the number of tiny flakes will increase.

In the traditional field, graphite is mainly used in machinery industry, chemical industry, metallurgy industry and light industry. It can be used as lubricants, friction materials, heat-conducting materials, various refractory moulds, anti-corrosion utensils, inks, pencils, etc. For example, natural graphite is mainly used in iron making and steel making (i.e. refractory materials); synthetic graphite is primarily used as an electrode in electric furnace steelmaking, and adding synthetic graphite powder to molten steel can increase the carbon content of iron.

As a valuable strategic resource, graphite has been used as early as the 16th century. With the development of science and technology, the field of application is continuously expanding. The discovery of graphene in 2010 and the extensive exploration and research of graphene and graphite structure in recent years, its excellent characteristics have shown its broad application prospects in many fields such as optics, energy, aerospace, environment, new materials, etc. Graphite is also gaining more and more attention. The application field of graphite will cross the traditional domain of application and turn to the implementation of strategic emerging areas such as aerospace, green environmental protection, nuclear industry, new materials, new energy and so on.
