Abstract : Impurities affect the metallurgical properties of refractory metals, and, thus, there is a need for reliable and accurate methods of analysis for these metals. An extremely selective and sensitive method was developed for the determination of trace amounts of zirconium in tungsten. The selectivity is attained by utilizing ion exchange in addition to liquid - liquid extraction techniques. The sensitivity is 5 ppm zirconium in tungsten. A method was also developed for the determination of trace amounts of titanium in tungsten. This method is not as selective as that for zirconium but is more sensitive. The sensitivity is 3 ppm titanium in tungsten. (Author)
