(Why can chromium oxide be used in petrochemical industry)

What is chromium oxide? There are several common chromium compounds: yellow-green crystal potassium dichromate (K2Cr207) with a ratio of 2.7; yellow crystal potassium trichromate (K2Cr04) with a ratio of 2.5; yellow crystal sodium chloride Na2CrO4 and &middot 10H2O; yellow crystal leadchromate PbCr04. Cr203 is formed from the above-mentioned chromium compounds. It can also be found in the colored oxide of glass, Cr203. Cr203 shares an area that is pure green with CuO. The cheap chromium-slag residue left over from the chromite process is commonly used in making bottles and containers. This is useful for producing ceramics. It can be used to make green glazes (adding basic lead color 2PbO), red glazes (adding PbCr04), grayglazed (adding ZnO) or yellow sleeves (adding TIO2). It’s the main raw material to produce green color cement.

The crystal structure of chromium dioxide

Cr2O3 is an aAl2O3-structured crystal. It’s composed of corundum-type voids made by the dense stacking of oxygenions and the filling with M ions. O2’s ionic radiations of Cr and O2 have been determined to be 0.132 and 0.069, respectively, 52 in the range 0.4140.732. As the coordination number for Cr+ is 6, a chromium Ion can be found in an octahedral space surrounded by six other oxygen ions. C2O3 crystal structure has oxygen ions at each location in the lattices of hexagonal crystals. Chromium ions reside within the octahedral space of hexagonal structures. Close-packed cubic and hexagonal crystals can each have one octahedral and two Tetrahedral gaps. This means that the closed-packed hexagonal structure includes six octahedral backyards. Electrical neutrality can be maintained by only two Cr2 pairs of three or less. The chromium and ions make up only 2/3 of the octahedral gaps. The composition ratio dictates that CP+ cannot fill all of the octahedral courtyards empty.

Utilization of chromium dioxide

High-temperature oxidation resistance is significantly increased by active elements such as Oxides with Cr.Y.ZrAl. This is because active elements, and their oxides, can dramatically reduce the amount of oxidized element critical for the alloy’s selective oxidation. It was found that the alloy’s resistance to oxidation is three times higher when a thin layer CnO3 – Y203 is placed on top of 1Cr18Ni9Ti.

Chromium oxide price

Price of Chromium Oxide will depend on its purity and size. The purchase volume may also have an effect on cost. Large quantities of small amounts will result in a lower price. On our official website, you can see the current price for chromium oxide.
