The Preparation And Features Of Chrome Oxide Green

Speaking from 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 can get chrome oxide green by thermal decomposition of ammonium bichromate. There is no doubt that Chrome Oxide Green Refractory can clarify every thing. That's for certain.

Now, let us speak something about characteristics or attributes of Chromium Oxide Green. Usually speaking, as some of us know, chrome oxide green is with the function of higher temperature resistance, light resistance. What’s more, it is with resistance to numerous chemicals. What’s more, if we make use of pure chrome oxide green, it's with the same infrared reflection as natural chlorophyll.

Speaking from the molecular weight of the Chrome oxide green, its molecular weight can be 151.99. what’s much more, it belongs to six square crystal system and it's using the shape of green powder. Consequently, we can also call 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 eight.5~9, which is close to the alumina (Al2O3) and second only to diamond. But its Mohs hardness is greater 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.five (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. 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.

On 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 particular, 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 also the boiling point can be 3000 DEG C. That is why we are able to say that chrome oxide green is really a type of things which belongs to high-quality refractory supplies. Chromic oxide is primarily used in metallurgy, paint, polishing, refractory supplies and new development of molten coating(which may be known as Chrome oxide green coating) and so on.
