Method of analysis of barium-calcium tungstates
Description
Analysis method of barium-calcium tungstates, including the treatment of the material analyzed with a solvent with subsequent determination of barium, calcium and tungsten ions in the solution using one of the known methods, is presented. For separate determination of BaO, Ba2CaWO6, Ba3WO6 and BaWO4 as selective solvents it is suggested that ethyl alcohol, distilled water, 0.3-10 mass % hydrochloric acid solution and 0.5-5 % citric acid solution should be respectively used
