【Abstract】 The ultra fine Calcium Silicate particles were prepared by airflow smash, ultra fine particles size and its shape were determined by LS230 laser granularity instrument and TEM. Calcium Silicate particles whose average size is about 1.1μm, particles size distributes between 0 4μm and 3μm, particles size and shape are consistent were gained. The results showed these ultra fine particles after airflow smashed are easy to form soft group, but they can be dispersed simply in the application.更多还原
