Why can chromium oxide be used in petrochemical industry

What is chromium oxide?

The molecular formula of chromium oxideis Cr203 oxide, with a molecular weight of 152, dark turf eco-friendly crystalline powder, a loved one density of 5.21, a melting factor of 1990 ℃, insoluble in water, slightly soluble in acid, as well as magnetic. Usual chromium substances consist of yellow-green crystal potassium dichromate K2Cr207 with a relative density of 2.7, yellow crystal potassium chromate K2Cr04 with a family member thickness of 2.5, yellow crystal salt chromate Na2CrO4 · 10H2O, yellow crystal lead chromate PbCr04. The above chromium salts are broken down into Cr203 under a minimizing environment; It is the tinted oxide of eco-friendly glass; Under the problem of solid oxidation, the quantity of high-valent chromium CrO3 is much more, that makes the glass yellow as well as eco-friendly; In a solid alkaline glass (such as high lead glass), the glass is tinted yellow generally by Cr03. Cr203 as well as CuO share an area of pure green. In creating containers as well as bottles, low-cost chromium slag (the deposit after chromite production) is commonly utilized. In the production of porcelains, it appropriates for making green polish, red glaze (including fundamental lead chromate 2PbO · PbCr04), grey glaze (including ZnO), as well as yellow sleeve (including TiO2). It is the raw material for manufacturing green shade concrete.

Crystal framework of chromium oxide Cr2O3 has an aAl2O3 structure, and this corundum-type crystal is composed of octahedral gaps developed by dense stacking of oxygen ions and dental filling of M ions. The ionic radii of Cr as well as O2 are known to be 0.069 nm and also 0.132 nm, respectively 52, in the variety of 0.414 ~ 0.732, so the sychronisation number of Cr+is 6, so in the octahedral space, a chromium ion is surrounded by six oxygen ions. In the crystal structure of C2O3, oxygen ions occupy the placements of each lattice of the close-packed hexagonal crystal, and chromium ions lie in the octahedral void of the close-packed hexagonal structure. In the close-packed hexagonal and also face-centered cubic crystal samples, each variety point can have one octahedral void as well as 2 tetrahedral yards, so the close-packed hexagonal structure consists of a total of six octahedral courtyards. To preserve electrical neutrality, just 2 Cr2 pairs of three o7. Therefore, just two-thirds of the octahedral space is occupied by chromium ions. CP+can only fill up two-thirds of the octahedral vacant courtyards according to the make-up ratio.

Use chromium oxide Oxides including Cr.Y.ZrAl and

other energetic aspects can considerably boost the high-temperature oxidation resistance of the alloy because these active elements and also their oxides can considerably lower the important content of oxidized elements required for discerning oxidation of the alloy. The experiment shows that the oxidation resistance of the alloy is enhanced by 3 times after the slim layer of CnO3 -Y203 is deposited externally of 1Cr18Ni9Ti. Price of chromium oxide Chromium oxide bit

dimension as well as purity will certainly influence the product ' s price,

and also the acquisition volume can also impact the cost of chromium oxide. A huge amount of huge quantity will certainly be lower.
