Evaluation of Surface Roughness of Fibrous Minerals by comparison of BET Surface Area and Calculated One

摘要

The Japan Fibrous Mineral Research Association (JFMRA) provides standard fibrous materials consisting of man-made mineral fibres (MMMFs), whiskers and a natural mineral fibre. In this research, the BET surface areas (SA_BET) of JFM standard samples as well as some other natural mineral fibres were measured by krypton gas adsorption. Calculated surface areas (SA_cal) were calculated from the measured length and width of individual fibres.
