摘要

β-SiAlON powder was prepared from silica-alumina gel and by heat-treatment in ammonia. Element analysis, X-ray diffraction, magic-angle spinning nuclear magnetic resonance, scanning electron microscopy and transmission electron microscopy were used to characterize the powder. It was found that nitridation reactions took place at 1100 C and β-SiAlON began to crystallize at 1300 C with mullite, O-SiAlON and χ-SiAlON as the intermediate phases. Nano-sized single phase β-SiAlON powder was obtained after heating at 1350 C for 3 h.
