Gamma spectrometry of liquids during step-by-step chemcial decomposition of activated ultradispersed titanium and aluminium nitrides

A device to carry out gradual chemcial decomposition of powdered materials activated in nuclear reactor with subsequent gamma-spectrometric analysis of liquid phase was suggested. Techniques of decomposition of titanium, aluminium nitrides and compositions on their basis, were developed. Employment of the techniques provides vast information on the character of impurity distribution in the given materials, as well as possibility to check the assumptions on chemical forms of the microimpurity presence. 11 refs.; 5 figs
