[Abstract]:The research progress in phase transition, electrical properties, activation modification, pressure transfer, whitening, color and coloring of pyrophyllite in recent years is summarized. The phase change products at high temperature, the determination of electrical conductivity and the process of activation modification are introduced. Factors affecting pressure transmission, whitening methods, coloring causes, low temperature coloring techniques, etc., in addition, in view of pyrophyllite in thermal physical properties, physical and mechanical properties, absorption spectra, electron paramagnetic resonance, The research progress of infrared and differential thermal analysis (DTA) and powder nanocrystallization are also briefly introduced. Finally, the deficiency of pyrophyllite performance research and the future development direction of pyrophyllite performance research are pointed out. It is clearly pointed out that the research on pyrophyllite performance needs to be further studied in breadth and depth; whitening technology needs to be improved in high efficiency, environmental protection and energy saving; the theory of nanometer powder needs to be mature, and the industrial application needs to be developed.
