Si-based oxynitride is an important type of structure/function integrated materials and has got wide applications in the fields of wear resistance, corrosion resistance, high speed cutting, pressure sealing, phosphors host, alkaline catalysis, and so on. The preparation of Si-based oxynitrides powders has undergone different development stages: high temperature solid state reaction (SSR), self-propagating high temperature synthesis (SHS), carbothermal reduction and nitridation (CRN), wet-chemical route combined with CRN, and others, presenting a sustained development trend. In this paper, the research progress in the activated-synthesis of Si-based oxynitrides powders and fibers at low calcination temperatures is reviewed over the past ten years, mainly focusing on the carbothermal reduction nitridation at micro-nano scale based on mesoporous template assembly as well as SiC reduction assisted Sol-Gel nitridation method. The development trend and applications of the low temperature activated-synthesis of Si-based oxynitrides materials are also prospected.
