硅灰石制高比表面积多孔SiO_2的扩大实验

Amplified experiment of high specicfic surface area porous silica prepared from wollastonite

进行了硅灰石制二氧化硅的扩大实验 ,物性测试表明 ,所得SiO2 比表面积超过 45 0m2 / g ,仍具有多孔性。与白炭黑质量国家标准相比 ,主要指标符合或超过标准。

Amplified Experiment in which silica was prepared from wollastonite was made.The characteristics measurements showed that the specific surface area of silica was more than 450m 2/g and porous still.Most of the indexes were accorded with or surpassed the national standard of white carbon.At the end,the application of the silica was discussed.
