The concentration of oxygen ions in the solution was modifying by dropping the calculated amount of BaO. Titration of Cr3+ chlorocomplex by O2? ions demonstrated the precipitation of CrOCl and Cr2O3. The solubility constants of these compounds were calculated. E–pO2? and three-dimensional E–pO2?–T type diagrams, which summarized the properties of chromium species in the melt, were determined.?? \\\\Cserver\\dist\\НБО\\Cтатьи БД ИВТЭ\\Electrochimica Acta\\EA2010 V. 55, N 17. - P.4960-4963.pdf |
