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.

Yes, the powder is green, the reason i want to dissolve it is that i have a huge qunatity of CrW powder
30% - 50 % Wolfram and the rest is chrome .

Thanks.
