Study of ground and unground leached vermiculite II. Thermal behaviour of ground acid-treated vermiculite
Original language description
In this study, we examined the annealing effect on the material obtained after acid treatment of ground vermiculite which constituted amorphous silica and ?-FeOOH. The XRD patterns of the starting sample measured at temperatures from 30 to 1200 °C showedthat the crystalline phase was present until 300 °C; whereas the sample heated between 300 and 800 °C was practically amorphous. This is in agreement with previous observations that ?-FeOOH decomposes to amorphous or poorly crystalline phase, ?-Fe2O3, and transforms only slowly to crystalline ?-Fe2O3. At 850 °C the sample showed the first signs of a crystalline phase which was fully developed at 1050 °C. The XRD, HRTEM and Mössbauer spectroscopy showed, after heating at 1050 °C, the presence of crystalline phase, consisting of quartz, cristobalite, ?-Fe2O3 and ?-Fe2O3.
