Electroconductive Carbon Black
Made up of primary carbon, carbon black is spherical in shape and arranged into aggregates and agglomerates. It differs from other carbon forms (diamond, graphite, Coke (fuel), coke) in its complex configuration, colloid dimensions and quasi-graphitic structure. Carbon black's purity and composition are practically free of inorganic pollutants and extractable organic substances. A distinction is made between these two terms: * Carbon black – a specially produced type of carbon using the process of incomplete combustion with restricted oxygen access. The article addresses this type of carbon. * Soot – auxiliary fuel (coal, hydrocarbons, crude oil) combustion product, which is considered to be a hazardous substance with carcinogenic properties. Carbon black can be characterized as a substance with over 97% amorphous carbon content. It is used extensively in many areas of industrial chemistry. It is often used in the plastic and rubber manufacturing industries, where it improves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon
Carbon () is a chemical element; it has chemical symbol, symbol C and atomic number 6. It is nonmetallic and tetravalence, tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth's crust. Three Isotopes of carbon, isotopes occur naturally, carbon-12, C and carbon-13, C being stable, while carbon-14, C is a radionuclide, decaying with a half-life of 5,700 years. Carbon is one of the timeline of chemical element discoveries#Pre-modern and early modern discoveries, few elements known since antiquity. Carbon is the 15th abundance of elements in Earth's crust, most abundant element in the Earth's crust, and the abundance of the chemical elements, fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Carbon's abundance, its unique diversity of organic compounds, and its unusual abi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
