用X射线粉末法和X射线盖革计数谱仪研究了共沉淀Ba、Sr、Ca三元碳酸盐的晶体结构。在BaCO 3 -SrCO 3 -CaCO 3体系中存在三种固溶体：文石型晶体（λ-碳酸盐）、方解石型晶体（β-碳酸盐）和球文石型晶体（μ-碳酸盐）。这三种晶型的相域在一定程度上受到沉淀温度的影响。在两个阶段的沉淀温度得到的三元图。
Crystal structures of the co-precipitated triple carbonates of Ba, Sr and Ca were studied by x-ray powder method using an x-ray Geiger counter spectrometer. There exist three kinds of solid solutions : aragonite type crystal (λ-carbonate), calcite type crystal (β-carbonate) and vaterite type crystal (µ-carbonate); in the BaCO 3 -SrCO 3 -CaCO 3 system. The phase domains of these three crystal forms are affected some-what by the temperature at which the precipitation is carried out. The triple diagrams are obtained at two stages of precipitation temperatures.
