In this paper, the reaction of Ni40Mn30Fe30 alloy and hydrous pyrophyllite obtained at different calcination temperatures under high temperature and high pressure was studied. The temperature was measured at 1420 ℃ and the pressure was measured to 5.5GPa. The physical-chemical mechanism of the reaction and the relationship between reaction rate and temperature, pressure and water content were studied. The inherent characteristics of material movement under high pressure are discussed.
