Study of ground and unground leached vermiculite II. Thermal behaviour of ground acid-treated vermiculite
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 ?-F...
