目前硅灰石的测定,都用间接法,即从酸溶全钙量减去石榴石、白云石、方解石中所含的钙,从而间接计算出硅灰石的含量。这样做容易带来各种误差。硅量法可直接测出硅灰石含量,方法简便快速、成本低。如仅测定硅灰石的含量时,无须测定其他项目。用本法测得的结果和钙量法测定结果是吻合的。一、方法依据根据测出的二氧化硅的含量,即可按硅灰石的组成〔CaO、SiO_2〕直接得出硅灰石 Wollastonite present determination, are used indirect method, that is, from the amount of acid-soluble calcium garnet, dolomite, calcite contained in the calcium, which indirectly calculate the wollastonite content. This is easy to bring about various errors. Silicon volume method can be directly measured wollastonite content, the method is simple and fast, low cost. If only the determination of wollastonite content, no need to measure other items. The results measured by this method are in good agreement with those obtained by the calcium method. First, based on the method based on the measured content of silica, you can follow the composition of wollastonite [CaO, SiO 2〕 directly derived wollastonite
