Carbon and graphite materials are nonmetallic solid materials with carbon as the main element, in which carbon materials are basically composed of non-graphite carbon, while graphite materials are basically composed of graphite carbon. For simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials).
Main characteristics of carbon:
The national technical standards and ministerial technical standards of carbon products in China are classified according to different uses and different production processes. This classification method basically reflects the different uses and production processes of products, and is also convenient for accounting, so its calculation method also adopts this classification standard.
The following introduces the classification and description of carbon products. The upstream enterprises in the carbon industry mainly include: anthracite calcination enterprises; Coal tar processing and production enterprises; Petroleum coke production and calcination enterprises.
Light weight, porosity, electrical conductivity, thermal conductivity, corrosion resistance, lubricity, high-temperature strength, heat resistance, thermal shock resistance, low thermal expansion, low elasticity, high purity and processability.
