Carbon information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.
Carbon in its elemental form is one of the softest (graphite) and hardest (diamond) materials found in nature. Applications for graphitic carbon include in lubricant formulations and as the replacement for lead in pencils. Diamond has numerous industrial applications due to its extreme hardness and resistance to heat and pressure. Graphene is a nanoscale ultra thin film or foil with thicknesses as small as 1 nanometer which can be produced from either silicon carbide or graphite flake processing. These include in drill bits and grinding media and grinding equipment. Carbon also finds application in steel alloys, in various filtering and purification technologies and as a neutron moderator in nuclear power plants. Carbon is available as a nanoparticle and in single-walled, double-walled and multi-walled nanotubes with purities from 99% to 99.999% ( ultra-high purity ). Carbon facts, including appearance, CAS #, and molecular formula and safety data, research and properties are
Oxides are available in forms including powders and dense pellets for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Carbon is available in soluble forms including chlorides, nitrates and acetates. These compounds are also manufactured as solutions at specified stoichiometries. Carbon is a Block P, Group 12, Period 2 element. The electronic configuration is [He] 2s2 2p2. In its elemental form carbon's CAS number is 7440-44-0. The carbon atom has a radius of 70.pm and it's Van der Waals radius is 170.pm.All elemental metals, compounds and solutions may be synthesized in ultra high purity (e.g. 99.999%) for laboratory standards, advanced electronic, metallurgy and optical materials and other high technology advantages. Information is provided for stable (non-radioactive) isotopes. Organo-Metallic Carbon compounds are soluble in organic or non-aqueous solvents. See Analytical Services for information on available certified chemical and physical analysis techniques including MS-ICP, X-Ray Diffraction, PSD and Surface Area (BET) analysis. Carbon was first discovered by Hans Christian Oersted in 1825.
