The Preparation And Features Of Chrome Oxide Green

Speaking of the preparation or supply of Chrome oxide green, we can get chrome oxide green by calcination of chromic acid, sodium bichromate (or potassium) or sulphur. What’s more, we are able to 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 traits or features of Chromium Oxide Green. Usually speaking, as a few of us know, chrome oxide green is with the feature of higher temperature resistance, light resistance. What’s more, it's with resistance to numerous chemicals. What’s much more, if we make use of pure chrome oxide green, it's with the 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 is with the shape of green powder. As a result, we can also contact it as Chrome Oxide Green Refractory powder. By the way, the density of Chromium Oxide Green can be 5.21g/cm3, and its Mohs hardness may be 8.5~9, that 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) two and zircon (ZrSiO4).

As for the refractive index of Chrome Oxide Green Pigment , its refractive index can be 2.five (coverage). And its specific 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. But it is slightly soluble in concentrated sodium hydroxide solution. What’s much more, it could 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 very stable for light, air, and corrosive gases (H2S, SO2). What’s much more, chrome oxide green is with superb weatherability. To become specific, when Green Chrome Oxide meets heat, it has good stability. In addition, the melting point of chrome oxide green can be 2265 DEG C and the boiling point can be 3000 DEG C. That is why we are able to say that chrome oxide green is a type of things which belongs to high-quality refractory supplies. Chromic oxide is primarily used in metallurgy, paint, polishing, refractory materials and new development of molten coating(which can be called Chrome oxide green coating) and so on.
