The invention discloses a high-flux material synthesis and synchronous radiation light source high-flux representing method of a composite material chip. A preparation method of the chemical compositematerial chip and a high-flux material preparation and representation combination system combined with synchrotron radiation light source X-ray diffraction station high-flux representation are utilized. Metal alkoxide, nitrate, acetate and chloride can be adopted as raw materials. According to the method, hundreds or thousands of samples can be prepared through a chemical method at a time, and the number of the samples can be regulated and controlled according to experiment needs. The crystal structure of the material can be fast and efficiently tested and analyzed through a synchronous radiation X-ray diffraction station high-flux representation automation platform. According to the preparation and representation system formed by combining a chemical composite material chip method and the high-flux representation automation platform, the preparation and representation speed of an inorganic material can be greatly increased, and the utilization efficiency of a synchronous radiation light source can be improved.
