DETERMINATION OF TRACE IMPURITIES IN ZIRCONIUM METAL BY A POINT-TO-PLANE SPECTROCHEMICAL PROCEDURE
Direct excitaiion of zirconium metal for the determination of aluminum, boron, cadmium, cobalt, chromium, copper, hafnium. iron, magnesium, manganese, molybdenum, nickel, lead, silicon, titanium, vanadium, and tungsten in the parts per million range is described. The required spectral sensitivity and reproducibility are obtained by exciting the sample with an iginited alternating current arc. Compared to other applicable methods, thc time for analysis and the opportunity for sample contamination are considerably reduced. Standard spectrochemical procedures are used for recording and computing results. With some changes in analytical lines and with adequate solid standands, the method can be extended to determination of impurities and alloying elements in Zircaloy. (auth)
