| Abstract: |
| The surface modification process of GCC in a stirring mill and the application of the modified GCC are described in this paper The study on the surface property of GCC with two modifiers is done Some measuring methods such as measurement of the specific surface area and contact angle and liquid wetting analysis are used for measuring the modified GCC powder qualitatively and quantitatively The results indicate that both AS and AA chemical adsorption occur on the surface of GCC considering the mechano chemical reaction,and the reaction made the filler particle size smaller and the filler specific surface area bigger |
