硅溶胶中二氧化硅粒径及比表面积测定

Measurements on the Diameter and the Specific Surface Area of Silica Particles in a Silica Gel

硅溶胶中二氧化硅粒度大小与尺寸分布对其性能有重大影响 ,为此提出了二氧化硅粒径与比表面积应成为硅溶胶的重要性能指标 ,并对二氧化硅粒径与比表面积的测定方法做了讨论。

The diameter and the specific surface area of silica particles,which have great effect on properties of silica gel,should act as a performance index.The methods which are de- termining the diameter and the specific surface area of silica particles had been discussed.
