Description
Thermal transformations of synthetic pyrophyllite prepared by thermal reaction and silica were investigated, using infrared spectroscopy, X-ray diffraction and thermal analysis. It has been found that an intermediate phase, i.e., dehydroxylate of pyrophyllite, is formed as a result of heating pyrophyllite within the range 500 to 800 deg C. A dehydroxylate of pyrophyllite is generally of the same structure as pyrophyllite. Decomposition of dehydroxylate into mullite and cristobalite stars at about 1000 deg C. The thermal transformations of synthetic pyrophyllite are compared with the thermal stability of natural pyrophyllite from South Africa. (author) 9 figs., 25 refs
