RI 5372 Determination Of The Average Effective Valence State Of Titanium In Sodium Chloride - Summary

Analytical methods are presented in this paper for determining soluble titanium, total titanium, indicated titanium, and average effective valence in titanium chloride - sodium chloride mixtures. In addition, data are given showing the effects of coarse and fine grinding on the degree of oxidation and average effective valence of such samples. INTRODUCTION The Electrometallurgical Experiment Station at Boulder City, Nev., as part of the Bureau of Mines program to obtain more efficient utilization of our natural resources, has been developing and improving titanium extractive metallurgical methods and techniques since 1945. Numerous reports have been published describing development of the Kroll process,4/ the electrorefining technique,5/ and methods of analyzing titanium sponge.6/
