Abstract Combustion synthesis is gaining importance as a means of producing ceramic materials from constituent powders with the borides, carbides and nitrides of the transition metals receiving the most attention. Impurities from the precursor powders and containment fixtures have been found to play significant roles in the quality of the final products. RBS, NRS, and PIXE have been used to: identify condensible impurities emanating from reacting samples; determine their concentrations on the precursor powders and product ceramics; and to positively identify TiO 2 as a major effluent during the TiC reaction. RBS and NRS have also been used in the analysis of oxide layers on the fine metal powders which are precursor materials for the combustion synthesis process.
