Abstract

INAA technique for the determination of impurities (O, F, Na, Mg, Al, Si, P, S, K, Sc, Cr, Mn, Fe, Co, Ni, etc.) and of some doping elements in molybdenum and tungsten with detections limits between 10−12 and 10−6g/g by using a nuclear reactor and a neutron generator have been developed. The methods have been used to control the products of processing of refractory materials, to study the dynamics of impurities and doping elements at all stages of the production process.
