Synthesis of aluminum-containing SiC（N） ceramic precursors is the key process of fabrication of high-strength SiC fibers. With a brief classification of polysilane， this paper summarizes the synthesis and characterization methods of aluminum-containing SiC（N） ceramic precursors， including using solid polysilane， liquid polysilane and polysilazane. Meanwhile， the influences of aluminum on ceramics are discussed from three aspects. Furthermore， the future perspectives of aluminum-containing SiC（N） ceramic precursors are proposed.
