Chrome oxide, also named green chrome oxide, has a relative density of 5.22, melting point: 2345℃, boiling point 4000℃, with pungent smell. It is mentioned its alias, from physical properties. Chrome oxide features a shape of light to deep green hexahedron crystal, to our surprising, when it turns brown in heat, after cooling nevertheless turns green. The crystalline is very difficult and steady, that is to say that the crystalline is passed into hydrogen even in red hot circumstances with out modifications. Morever, it is insoluble in heating potassium bromate answer, a little insoluble in acid and alkalis and practically insoluble in water,alcohol and acetone.
Because of
chrome oxide's unique chemical properties,please put on suitable protective
clothes and gloves to avoid speak to with skin and eyes when we are using
them.In case of accident or if you feel unwell, seek medical suggestions right
away and just limited evidence of carcinogenic impact. Nevertheless, with the
speedy improvement of economy,the level of the people's living standards is
improving, as well as the science and technology are also quickly develop.
According to the statistics, Green Chrome
Oxide is mainly used for smelting metal
chrome and chrome carbide. Chrome oxide price(Chromium Oxide
Price) is determined
by different adaptabilities, some even extremely 40,000 per kilogram.It
extensively serves as a colorant for enamel、ceramics、artificial leather and building material, especially
apply to ceramic pigment make the ceramic colorful and well-designed. As paint
raw material, we should think that there is a wonderful perspective for chrome
oxide and the chrome oxide cost still is in a larger level. Beside above, it is
application for oganic chemical synthesis catalysts、sunproof piant、abrasive
substance、green polishing
paste as well as the printing of paper currencyx in particular ink.Even this,
the chrome oxide is also developed refratory like high-chromium brick,chrome
corundum brick. These refractories need fused chrome oxide as
fundamental.materials. Nonetheless,added quantity is not large, however it can
execute some signifiant of material, for example high temperature strength,
excellent slag resistance along with the thermal shock stability. Within the Chromium Oxide is
added to other refractory materials, can considerably increase the higher
temperature properties of refractory supplies. There's a document showed that
fused chromium oxide raw supplies are utilized in dense, as a result of
decreased stomatal castable refractory material rate, so the ready with
corrosion resistance and slag resistance of permeability, durability
significantly enhance.
Green chrome
oxiden lives in our life everywhere and it truly is our important fundamental
chemical solution. Within the meantime,we need to comprehend the problem we
must face is we do not have a bottomless pit of sources, something is to be
within a suitable way in an effort to save our residence and till live much
better with each other.
