Application of the K0 standardization method in neutron activation analysis of ceramic materials

An analytical procedure has been developed for neutron activation analysis of ceramic powders, it is mainly based on the application of the K0 standardization method and on the use of pelletizing for sample preparation. Precision and accuracy have been checked through the analysis of international standards. The procedure was applied to a commercial silicon carbide sample for the determination of 42 elements. Results were interpreted in terms of repeatability and accuracy by comparison to other trace analysis techniques. Additional short half-life elements were also determined by the K0 method.
