Targeted synthesis ultrafine α- and γ-Bi2O3 having different morphologies

Reactions of nitric acid solutions of bismuth with alkalis have been studied. The effect caused by coprecipitation conditions in the presence of additional agents (EG, PEG 400, or PEG 8000) and without on the phase composition and morphology of α- and γ-Bi2O3 has been determined.
