Description	The purpose of the present study was modification the surface and structural properties of natural talc for its further use into nanocomposites. Therefore the combination of different mechanical and chemical treatments was utilized. Talc powder was dry milled by vibration and planetary ball mill. Then the samples were acidified or alkalized with hydrochloric acid or sodium hydroxide. The specific surface area (SSA) and cumulative pore volume (Vcp) values of the starting material were 10.1 m2/g and 0.09 cm3/g. It was found that the acid treatments caused an increase of the specific surface area, while the alkali actions caused a decrease in the SSA. The highest SSA (24.1 m2/g) was measured for sample Tv6H after vibration milling and subsequently treatment with 6 M HCl. A slightly increase in the Vcp was observed for all prepared samples. The untreated and treated samples were examined in terms of their X-ray diffraction, specific surface area and particles size distribution.
