| Abstract |
| Chromic oxide is largely used as a green pigment in various
industrial and commercial purposes, as it is the only green
pigment which can withstand the Chemical reactions of both
acidic and alkaline media. It is the only permanent green
colour for Cements. distempers and artists paints. The other
greens like Brunswick green and Mountain green are not so
durable. Chromic oxide or Cr203 can also stand high
temperature and for this reason it is used for colouring glass,
enamels and pottery glazes. It is also used in Calico printing
as it is not affected by chlorine and sulphur gases. This pigment
has a good.covering power and can be mixed with other pigments
without any chemical alteration. |
