Description

Black powder or crystals; [Sax]

Sources/Uses

Stable isotopes are C-12 (98.892%) and C-13 (1.108%) [Merck Index] Carbon is activated chemically or by steam. Activated carbon that is 99.9% pure is available. [CHEMINFO] Used in purifying metals, cleaning air, and as a pigment for rubber tires and inks; [HSDB] Carbon nanotube (CNT) applications include electronics, reinforced rods, polymer activators, biosensors, and electron microscopy; [PMID 21191487] "CNTs are several times stronger than steel at the same weight; and they provide excellent thermal and electrical conductivity. CNTs are used in composites, aerospace, electronics, and energy applications." [PMID 21654426]

Comments

Dust explosions are possible when the powder is mixed with air; [ICSC] Wet, activated carbon can remove oxygen from a confined space. [CHEMINFO] Carbon nanotubes of sufficient length and aspect ratio can induce asbestos-like responses in mice. [Reference #1] "There is sufficient evidence in experimental animals for the carcinogenicity of MWCNT-7 multiwalled carbon nanotubes." [IARC Monographs - 111] See "Graphite, all forms except graphite fibers," "Carbon black," and "Carbon-14."
