The Preparation And Attributes Of Chrome Oxide Green

Speaking of the preparation or supply of Chrome oxide green, we are able to get chrome oxide green by calcination of chromic acid, sodium bichromate (or potassium) or sulphur. What’s more, we can get chrome oxide green by thermal decomposition of ammonium bichromate. There is no doubt that Chrome Oxide Green Refractory can explain everything. That's for sure.

Now, let us talk something about characteristics or features of Chromium Oxide Green. Usually speaking, as some of us know, chrome oxide green is using the feature of higher temperature resistance, light resistance. What’s much more, it is with resistance to various chemical substances. What’s more, if we make use of pure chrome oxide green, it's using the exact same infrared reflection as natural chlorophyll.

Speaking of the molecular weight of the Chrome oxide green, its molecular weight may be 151.99. what’s much more, it belongs to six square crystal system and it's with the shape of green powder. As a result, we can also call it as Chrome Oxide Green Refractory powder. By the way, the density of Chromium Oxide Green may be five.21g/cm3, and its Mohs hardness may be eight.5~9, which is close towards the alumina (Al2O3) and second only to diamond. But its Mohs hardness is more than silica and topaz al2 [SiO4] (F, oh) 2 and zircon (ZrSiO4).

As for the refractive index of Chrome Oxide Green Pigment , its refractive index may be 2.5 (coverage). And its particular heat (when the temperature is twenty degree) may be 0.17J/ (G - K).

What’s much more, chrome oxide green is insoluble in water, acid and organic solvents. However it is slightly soluble in concentrated sodium hydroxide answer. What’s much more, it can be dissolved in hot sodium bromate answer and heat concentrated perchloric acid solution or boiling parathion mixed acid.

Around the other hand, Chrome Oxide Green Dye is extremely steady for light, air, and corrosive gases (H2S, SO2). What’s much more, chrome oxide green is with superb weatherability. To become particular, when Green Chrome Oxide meets heat, it has good stability. Additionally, the melting point of chrome oxide green can be 2265 DEG C and also the boiling point may be 3000 DEG C. That's why we are able to say that chrome oxide green is a kind of things which belongs to high-quality refractory materials. Chromic oxide is primarily used in metallurgy, paint, polishing, refractory supplies and new improvement of molten coating(which may be called Chrome oxide green coating) and so on.
