The Preparation And Attributes Of Chrome Oxide Green

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

Now, let us talk some thing about characteristics or features of Chromium Oxide Green. Generally speaking, as a few of us know, chrome oxide green is with the function of higher temperature resistance, light resistance. What’s much more, it's with resistance to numerous chemicals. What’s more, if we make use of pure chrome oxide green, it is using the exact same infrared reflection as all-natural chlorophyll.

Speaking of the molecular weight from the Chrome oxide green, its molecular weight can be 151.99. what’s much more, it belongs to six square crystal method 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 five.21g/cm3, and its Mohs hardness can be eight.5~9, which is close to 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 2.5 (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 solution. What’s 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 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. Additionally, 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 can say that chrome oxide green is a kind of things which belongs to high-quality refractory supplies. Chromic oxide is primarily used in metallurgy, paint, polishing, refractory materials and new improvement of molten coating(which can be known as Chrome oxide green coating) and so on.
