A chemical method for determination of the charge state of chromium in B2O3-based materials (Bi12SiO20 and Bi12TiO20 single crystals) in a wide Cr concentration range (1 × 10−5 − 2 × 10−2 wt.%)is proposed. The method is based on a color reaction between Cr6+ and diphenylcarbazide in an acid medium.
