How can i dissolve chrome oxide ?
Yes, the powder is green, the reason i want to dissolve it is that i have a huge qunatity of CrW powderLou said:I’m presuming you mean green Cr2O3/Cr(III) not CrO3 which is very nasty (oxidizer, strong acid and very orange).
Cr2O3/chromia is not easily dissolved and much depends on its heat history. I would try hot dilute sulfuric.
Makes a great refractory.
