Other Experimental

Sublimates at 3652-97 °C;X-ray diffraction reveals a structure similar to, but less regular than graphite; particle sizes from 5-500 nm; appear spherical under electron microscope;The surface area, dimensions, and distribution of the pores depend on the precursor and on the conditions of carbonization and activation. Pore sizes are classified by the International Union of Pure and Applied Chemistry (IUPAC) as micropores (pore width > 50 nm), mesopores (pore width 2-50 nm), and macropores (pore width >50 nm).;Adsorption capacity and rate of adsorption depend on the internal surface area and distribution of pore size and shape but are also influenced by the surface chemistry of the activated carbon.;An amorphous form of carbon characterized by high absorptivity for many gases, vapors, and colloidal solids. ... porous internal structure (honeycomb-like). The internal surface area of activated carbon averages approximately 10,000 square feet per gram. ... It is not effective in removing ethylene.;Properties of U.S. Activated Carbon [Table#3779];Atomic number: 6; valence: 4; stable isotopes: 12 (98.892%); 13 (1.108%); radioactive isotopes: 9-11; 14-16;Nonmetallic element; divalent forms are known (carbenes); forms binary compound called carbides with many metals and some nonmetals ... strong reducing agent ... strong electrical conductivity;ATOMIC RADIUS: 0.77 A; IONIC (CRYSTAL) RADII: 2.60 A (-4 OXIDATION STATE); 0.15 A (+4 OXIDATION STATE); ORBITAL ELECTRONS: [HE]2S2-2PS; ELECTRONEGATIVITY (PAULING SCALE): 2.5;Specific gravity: amorphous 1.8 to 2.1; graphite 1.9 to 2.3; diamond 3.15 to 3.53 (depending on variety);AMORPHOUS BLACK CRYSTALS; INSOL IN WATER, ACID, ALKALI; DENSITY: 1.8-2.1; BP: 4827 °C; SUBLIMES: 3652-3697 °C /AMORPHOUS/;Colorless, cubic crystals; MW: 12.011 insoluble in water; density: 3.51; MP: 4440 °C (12.4 GPa) /Diamond/;Colorless mineral ... color can vary between pink, light blue and even black due to incorporated impurities /Diamond/;MW: 760.642 Yellow needles of plates.

Soluble in benzene, toluene /Fullerene-70/;A new brittle form of carbon ... can be obtained with high purity. It has high resistence to corrosion, has good thermal stability and is structurally impermeable to both gases and liquids. It has a randomized structure, making it useful in ultra-high technology applications, such as crystal growing, crucibles for high-temperature use, etc. /Glassy carbon/;The (12)C isotope, which comprises 99% of the element, is the standard to which atomic weights of all other elements are referred (C = 12.00 exactly). One mole of carbon atoms (6.02x10+23) is contained in 12 g of (12)C.;In 1969 a new allotropic form of carbon was produced during the sublimation of pyrolytic graphite at low pressures. Under free-vaporization conditions above approximately 2250 deg K, "white" carbon forms as small transparent crystals on the edges of basal planes of graphite. ... "White" carbon is a transparent birefringent material. Little information is presently avail about this allotrope. /"white" carbon/;Of recent interest is the discovery of all-carbon molecules, known as "buckyballs" or fullerenes ... consisting of 60 or 70 carbon atoms linked together, seem capable of withstanding great pressure and trapping foreign atoms inside their network of carbon. ... said to be capable of magnetism and superconductivity and have potential as a nonlinear optical material. Buckyball films are reported to remain super-conductive at temperatures as high as 45 k.;The element carbon, due to its high heat capacity per unit weight, high energy of vaporization, and high temperature and pressure required for melting, has the highest "heat of ablation" (energy absorbed per mass lost) of any material, provided that mechanical removal of particulates does not occur.;The apparent density of beech charcoal is 0.45 g/mL and that of pine charcoal is 0.28 g/mL; the density of pore-free charcoal ranges between 1.38 and 1.46 g/mL, depending on the kind of wood; the porosity of beech charcoal is ca 70%; the bulk density of charcoal, which depends on the kind of wood and the size of the pieces, ranges from 180 to 220 kg/cu m; the heating value ranges between 29 and 33 kJ/g;Graphite is one of the softest known materials while diamond is one of the hardest. Graphite exists in two forms: alpha and beta. These have identical physical properties, except for their crystal structure. Naturally occurring graphites are reported to contain as much as 30% of the rhombohedral (beta) form, whereas synthetic materials contain only the alpha form. The hexagonal alpha type can be converted to beta by mechanical treatment, and the beta form reverts to the alpha on heating it above 1000 °C.;Liquid molar volume = 0.007455 cu m/kmol;Heat of formation = 7.1668X10+8 J/kmol;Heat of fusion = 1.0460X10+8 J/kmol at melting point
