Carbon black is an elemental carbon in the form of virtually pure colloidal particles that are produced by incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons under controlled conditions. Nanoparticles have a particle size of less than 100 nm in any direction. XCO:0001773 controlled air CB nanoparticle content experimental_condition_ontology slaulederkind
