Carbon Graphite is a type of non-metallic material composed of carbon elements. It has a variety of allotropes, including diamond, graphite, carbon 60 (fullerene) and amorphous carbon (such as charcoal, coke, activated carbon, etc.) .
Physical and chemical properties
Graphite: It belongs to the hexagonal crystal system. Each layer is composed of hexagonal rings. The layers are parallel to the layers, showing an orderly overlapping crystal structure. Graphite has good electrical conductivity, thermal conductivity and lubricity, and is often used in high-temperature and high-strength components, electrodes for electric arc furnace steelmaking, etc.
Diamond: It belongs to the tetrahedral structure of the cubic crystal system and is the hardest substance in nature. Diamond also has good electrical and thermal conductivity, but its physical properties are significantly different from graphite.
Carbon 60 (fullerene): is a spherical molecule composed of 60 carbon atoms that has special structural and electronic properties and is commonly used in materials science and nanotechnology.
Amorphous carbon: Does not have an orderly arrangement like graphite and is commonly used in fuels, decolorants, and catalysts for chemical reactions.
