| Abstract: | In this paper the reaction conditions in which sodium fluoride and white carbon black were prepared in Na2SiF6 -Na2CO3-H2O system were studied.The sodium fluoride which was prepared from once-through operation under the ordi nary pressure reached the ministry-issued standard of second-class products and additional 10% NaOH treattment would lead sodium fluoride to the first-rate product. The white carbon black obtained also reached the quality standard of goneral-class products. |
