Thermal Behavior of Ground Talc Mineral

Microstructure development and thermal behavior of ground talc mineral samples (from locality Puebla de Lillo,Spain) was characterized by X-ray diffraction, scanning electron microscopy(SEM),surface area measurements differential thermal analysis, thermogravimetry and emanation thermal analysis (ETA). A vibratory mill and grinding time 5 min. was used to prepare the ground talc sample. It was found that grinding…
