Mar 01, 2006 · Grinding for 6 h and subsequent leaching for 2 h of raw talc produced the porous silica with a specific surface area of 133 m 2 /g and total pore volume of 0.22 ml/g. The increase in specific surface area ( S BET ) of the porous silica reflected the formation of micropores of 1.2∼1.8 nm and mesopores of 4.0∼5.5 nm in diameter inside the porous structure

effect of combined mechanical and ultrasonic milling on

Jul 16, 2019 · This study aims to investigate the effect of combined mechanical and ultrasonic milling on the size reduction of talc. Firstly, the talc sample was wet ground in a stirred media mill for five different times (30, 60, 90, 120, and 150 min), and the optimum result was subsequently achieved with treatment by ultrasonication. The effects of amplitude (20, 35, and 50 μm), solid content (2.5, 5, 7

physicochemical properties and surface free energy of

Aug 31, 2004 · The polar part of surface free energy (γ p) was considerably increased after 10 min of grinding (γ p: intact talc 4.7→10 min ground talc 12.1 mN/m). The change in the polarity (γ p /(γ p +γ d)) was also observed by the grinding. The polarity of intact talc was 26%. The polarity was increased to 41% by 10 min of grinding of talc
