Synthesis of Specific Surface Area Standard Reference Materials of Nonporous Mono-disperse SiO_2 Spheres

从单分散二氧化硅(SiO2)微球的合成方法、粒度表征、定值及其组装体几何比表面积的计算等几个方面对SiO2比表面积标准物质的合成进行了总结。这种类型比表面积标准物质的合成不仅可以扩展我国比表面积标准物质的种类,而且将有助于加深人们对物质真实比表面积的进一步认识。

In this paper, the synthesis of the standard reference materials of specific surface area （SRMS） including the synthesis of mono-disperse silica particles, determination and fixed value of the granularity and the calculation of the assembly geometrical specific surface area were summarized. This kind of standard reference materials of specific surface area can not only expand the species of the SRMS in China, but also help understand the true specific surface area of materials deeply.
