The Preparation And Features Of Chrome Oxide Green

Speaking of the preparation or source 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 isn't any doubt that Chrome Oxide Green Refractory can explain everything. That is for certain.

Now, let us speak some thing about characteristics or attributes of Chromium Oxide Green. Generally 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 chemical substances. What’s more, if we make use of pure chrome oxide green, it's with the exact same infrared reflection as all-natural chlorophyll.

Speaking from the molecular weight from the Chrome oxide green, its molecular weight may be 151.99. what’s more, it belongs to six square crystal system and it's using the shape of green powder. Consequently, we are able to also contact it as Chrome Oxide Green Refractory powder. By the way, the density of Chromium Oxide Green may be 5.21g/cm3, and its Mohs hardness may be eight.5~9, that 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 can be 2.five (coverage). And its specific heat (when the temperature is twenty degree) can 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 answer. What’s 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 extremely steady for light, air, and corrosive gases (H2S, SO2). What’s more, chrome oxide green is with superb weatherability. To become specific, when Green Chrome Oxide meets heat, it has great stability. Additionally, the melting point of chrome oxide green can be 2265 DEG C and also the boiling point can be 3000 DEG C. That's why we can say that chrome oxide green is a kind of things which belongs to high-quality refractory supplies. Chromic oxide is mainly used in metallurgy, paint, polishing, refractory supplies and new improvement of molten coating(which can be called Chrome oxide green coating) and so on.
