The determination of titanium in lead zirconate-lead titanate electronic ceramics [electronic resource] : a comparison of titrimetric methods with polarographic and differential spectrophotometric methods / A. Hitchen, Extraction Metallurgy Division. Ottawa : Information Canada, 1972. iv, 35 p. Technical bulletin ; TB 153 Cover title. "October 1972." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “Three procedures for the determination of titanium in lead zirconate-lead titanate powders and process solutions which are simple, rapid, precise and accurate, are described. Two of the methods are based on reduction of the titanium with a) liquid zinc or lead amalgams or b) metallic aluminum, followed by titration of the reduced titanium with a standard ferric sulphate solution using sodium thiocyanate as the indicator. The third method is a polarographic procedure using an acetate + EDTA electrolyte. Relatively few elements interfere and procedures are suggested to overcome some of those that do. The accuracy and precision of the methods compare favourably with the much longer differential spectrophotometric method"--Abstract, p. i.
