本文在用硅灰石与盐酸反应制备高比表面积 Si O2 (比表面积大于 4 0 0 )的基础上 ,较系统地讨论了制备过程中的反应速度、反应时间、中和速度和反应最终 p H值四要素对产物比表面积的影响 ,并初步确定了最佳实验工艺条件。
In this paper, the reaction of wollastonite and hydrochloric acid to prepare high specific surface area Si O2 (specific surface area greater than 400), based on a systematic discussion of the reaction process in the preparation of the reaction speed, reaction time and reaction final p H The value of four factors on the product surface area, and initially determine the best experimental conditions.
