摘　　要：本文采用X-射线衍射K值法测定了硅灰石矿中方解石的含量,测定时选用高纯度的硅作为标样,碳酸钙为参比物质,测得的K值为2.027,并用此K值测定硅灰石矿中方解石的含量,结果相对标准偏差分别为0.78、1.1、0.74,与其他方法相比,较吻合。The Calcite content in Wollastonite was determined by K value method of x- my diffraction,the high purity silicon is the reference standard substance, the calcium carbonate is the contrastive substance, so the K value is 2.027, which is used to measure the Calcite content in Wollastonite, the results of K value method of x - ray diffraction show the relative and standard deviation is 0.78、1.1 、0.74 respectively.
