Chromium
Oxide Green is a type of Six Celebration of crystal or amorphous dark green
powder having a metallic luster. There are usually two colors about it: pale
olive green and dark olive green. Chromium
Oxide Green has excellent heat resistance and will not change color at a
temperature of 1000 degrees. It also has good acid resistance and alkali
resistance. It's insoluble in water and acid, and soluble in hot alkali bromate
solution.It is very stable to light, air and sulfur dioxide and hydrogen
sulfide as well as other corrosive gases. Additionally, it has a higher hiding
energy, however the tinting strength is weaker than phthalocyanine green, and
also the colour is not vibrant sufficient. Meanwhile, it features a difficult
size along with a worse paint gloss slightly. It's magnetic and toxic.
Green Chrome Oxide has high covering energy
and magnetic. Its color and lustre relate towards the dispersity of its
crystalline particle. When the dispersity of its crystalline particle is fine,
it is vibrant green; and it'll close to black when the dispersity of its
crystalline particle is thick. The Chrome
Oxide will change into brown when it is heated, and can change back to
green when it cool down. It's usually used in creating fine bearing of precise
instrument, watch and instrument industries. Additionally, it can be used as
catalyst in organic synthesis.
Green Chrome Oxide may also be used in
coloring for ceramics, enamel and rubber. It may be used to create coating of
high temperature resistant and art paint, or used in making printing ink which
is utilized in printing cash and negotiable securities. Inside a word, it is
really a kind of advanced green ink. The colour of green Chromium Oxide Green is comparable to
chlorophyll, and may be used for camouflage paint and make the issues tough to
distinguish at infrared photography.
Additionally, Chromium Oxide Green may also be used
as a cosmetic colorants, and mainly for the makeup of eyes. But it should not
use within the makeup of mouth and lip, and additionally, it not be recommended
for facial cosmetics and nail polish. At the same time, it is 1 of major
elements of silver plated layer vibrant dipping liquid, and is an essential raw
material for preparing chromium fluoride and chromium bromide.
Within the other hand, please pay attention
to that chromium compounds have local stimulating effect on the skin and can
trigger ulcer when you use it. It will cause cartilage of nasal septum
perforation and damage the respiratory organ whenever you inhale it. It even
may cause pneumosclerosis. At the same time, Chromium Oxide Green is somewhat
dangerous towards the water. Don't let undiluted or big amounts of chromium
compounds get in touch with with groundwater undiluted. And don?¡¥t discharge
it into surrounding environment with out the permission from the government.d
do not discharge it into surrounding atmosphere with out the permission from
the government.
