  rdf:value "Sedimento pulverulento oscuro de residuos de combustible sin quemar, compuesto principalmente por carbono amorfo y algunos hidrocarburos, que se acumula en las chimeneas, los silenciadores de los automóviles y otras superficies expuestas al humo. Es el producto de la combustión incompleta de combustibles orgánicos ricos en carbono en condiciones con bajo nivel de oxígeno. En ocasiones se le denomina negro de humo o negro de carbón y es usado en la fabricación de tintas, llantas de hule y nanotubos de carbono."@es, "A dark powdery deposit of unburned fuel residues, composed mainly of amorphous carbon and some hydrocarbons, that accumulates in chimneys, automobile mufflers and other surfaces exposed to smoke. It is the product of incomplete combustion of carbon-rich organic fuels in low oxygen conditions. It is sometimes called lampblack or carbon black and is used in ink, in rubber tires, and to prepare carbon nanotubes."@en ;
