In order to determine larger quantities of zirconium in its borides and nitride (most of which are soluble in sulfuric acid) it is suggested the material be titrated with trilon and complexon surplus be backtitrated with nitric bismuth salts. Thiourea is used as indicator at pH 2. In this way up to 90% zirconium can be determined with an accuracy of plus or minus 0.4%. The analysis can be carried out in the presence of sulfuric acid and other acids as well as the majority of bivalent cations. Zirconium forms a number of different complex compounds with trilon. It was also observed that white insoluble compounds form which are dissolved when being heated. The analysis process is described. (TCO)
