Difference between carbon and carbon and carbon and graphite

For a long time, it felt like the use of charcoal and carbon was confusing. However, from a chemical point of view, carbon and carbon have a strict essential difference and scope of use.

However, any pure substance that can embody the properties of carbon elements or carbon atoms, or compounds composed of carbon atoms or carbon ions or other ions or ionic clusters, is always "carbon" next to the stone character in the name. For example: carbon element, carbon atom, carbon sixty, nanocarbon, carbon isotope, carbide, aromatic carbon, primary carbon, terminal carbon, carbon dioxide, carbon content, carbon steel, carbohydrates, hydrocarbons, carburizing, amorphous carbon, other compounds of carbon, etc.

Where the properties of carbon elements or carbon atoms are not fully reflected, or where a mixture of carbon atoms or carbon compounds is formed, "charcoal" is used in the name of the expression. Such as: charcoal, coal, coke, activated carbon, glass charcoal, pyrolysis carbon, biochar, carbon brick, carbon block, carbon graphite material, carbon rod, carbon rod, homogeneous carbon, carbon black, carbon paste, carbon plant, carbon slag, carbon material, carbon electrode, carbon paste, etc.

Definition and classification of carbon materials

Broadly speaking, carbon materials are collectively referred to as all pure carbon materials and carbon substances containing carbon mixtures.

In a narrow sense, carbon materials refer to inorganic materials obtained by selecting graphite or amorphous carbon as the main solid material, supplemented by other raw materials, and obtained through a specific production process.

Carbon materials mainly include carbon raw materials and carbon products.

Carbon raw materials mainly include coal, coke, petroleum coke, coal asphalt, graphite, diamond, coal tar and so on.

There are many kinds of carbon products, with different specifications, models and material properties, and they are widely used. Due to the different uses of the product, there are differences in the raw materials and processing technology used, and there are obvious differences in the physical and chemical properties of the product itself.

Carbon products can be divided into carbon products, semi-graphite products, natural graphite products and artificial graphite products according to the material. According to the use function, it can be divided into three categories: conductive materials, structural materials and special functional materials.

Conductive materials

Graphite electrodes, carbonaceous electrodes, natural graphite electrodes, electrode pastes and anode pastes, brushes and calcium carbide flowers, mold materials for processing, carbon rods for dry batteries.

Materials of construction

Such as iron-making reduction furnace, ferroalloy furnace, calcium carbide furnace, aluminum electrolytic cell side carbon brick, refining furnace and related purification furnace lining, nuclear reactor deceleration materials and reflective materials, chemical supply of corrosion-resistant equipment, wear-resistant materials in the machinery industry, graphite lining for continuous casting in steel and non-ferrous metal smelting industry, semiconductor and high-purity material smelting devices, etc.

Special functional materials

Biochar, implicit aircraft materials, all kinds of pyrolytic carbon and pyrolytic graphite, recrystallized graphite, carbon fiber and its composite materials, graphite interlayer compounds, nanocarbon, etc.
