Talc properties after acid treatment and mechanical procedures

Popis výsledku v původním jazyce

The effect of different mechanical treatments in combination with inorganic/organic acid treatments on the structure of natural talc was purpose of this work. The mechanically and chemically treated samples were investigated by measurement of specific surface area, X-ray diffraction and Infrared spectroscopy. Mechanical procedures and inorganic/organic acid treatment led to reduction of particle size and to increase of the specific surface area. The value of SSA increased three-times (31.83 m2/g) for sample TvsH in comparison to initial talc (T) sample (10.10 m2/g). The sample TvsH was prepared from talc (T) by combination grinding (v) and sonication (s) and subsequent acid activation with strong hydrochloric acid (H). The sample TvsH showed the smallest particle size 0.067 ?m among all prepared samples which reduced from initial particle size 0.212 ?m of T.
