From the standpoint of new materials and technologies exploration, the preparation methods, formation mechanisms and application prospects of several kinds of inorganic functional materials （ ZnO, ZnS, LiNbO3 , copper salt compounds and magnesium salt compounds） have been summarized. Through adopting liquid phase method, designing original synthesis technology and reasonably regulating and controlling the microhabitat of particles of the functional materials, the optimization on material＇s topography, size and performances has been realized, which pushed the production of new materials on a large scale. The key factors that affect the performance and topographical structure of the products, such as the species of reactant, reactive temperature, the selection of hydrothermal and room temperature treatment and the addition of controlling agent of crystal form etc. are discussed in detail in this paper. The liquid phase method is environment - friendly and easy to operate, which is the best way to synthesize inorganic functional materials.
