TL;DR: In this article, the relative amounts of anatase and rutile in mixtures were determined using diffractometry, and a method using the more precise technique of diffraction was developed.
Abstract: ITAXIUM DIOXIDE may be incorpoT rated into a plastics molding compound to adjust the dielectric constant to a desired value. Either anatase or rutile may be used; these allotropic forms differ in dielectric behavior. Xeither is available commercially in a pure state; a preparation consisting largely of one form is apt to contain, in addition to other impurities, an admixture of the other. In order to permit proper formulation of filled resins, therefore, it is desirable to establish a method for determining the relative amounts of anatase and rutile in mixtures. The application of photometry to this problem has been discussed (2,6). This paper develops a method using the more precise technique of diffractometry.

TL;DR: In this paper, a new anionic liquid-liquid extraction technique uses solutions of long-chain amines in chloroform to extract acids on complex metal acids from aqueous solutions.
Abstract: A new anionic liquid-liquid extraction technique uses solutions of long- chain amines in chloroform to extract acids on complex metal acids from aqueous solutions. Extractions of some anionic complexes of Pe, Fu, Zr, and Pa are demonstrated. (auth)
