Carbon black is produced due to incomplete combustion of
heavy petroleum products. It is used in rubber as pigment thats how it gets its black
color. (e.g Tyres). Also used in printers, toners etc. It is AMORPHOUS form of carbon,
that is without definite shape.
Nano particle: Anything of
size in the order of 10^-9 metre is a nano particle. CBNP's are considered carcinogenic
as they kill cells in our lungs on prolonged exposure. Currently research is on to link
its contribution to global warming too!
Carbon black, in my
opinion, is INORGANIC. Carbon black has Graphite content that varies depending on the
process of its production. Graphite in turn is considered Inorganic despite being an
allotroph of carbon (IUPAC Red book). Most carbon-containing compounds are organic, and
most compounds with a C-H bond are organic. Not all organic compounds necessarily
contain C-H bonds
