| Abstract: | The preparation of graphite Raschig ring by a sintering process using the colloidal graphite as main raw material is reported in this paper. Effects of the adhesive used, the technology of the forming process and heat treatment process on the characteristics of graphite Raschig ring were studied thoroughly. The structure of graphite Raschig ring was analyzed by SEM. It is proved that the properties of the graphite Raschig ring prepared in our laboratory are better than those of the imported products. |
