Abstract

Gas reduction-nitridation (GRN), which uses a mixture of NH_3 and carbohydrate as a reactant gas, has been proposed a synthetic technique for producing high-purity nitride powders. In this study, β-SiAlON powder was produced from zeolite using GRN. Zeolite was used directly as the raw material without previous preparation or handling. It was found that high purity β-SiAlON nanopowder was synthesized at 1400℃ for 60 min. Furthermore, pure β-SiAlON was successfully produced, containing no minor phases, by the optimization of nitridation, that is, of concentration of C_3H_8 and the timing of its introduction.
