测定混合物中方解石、文石和球文石的碳酸钙多晶型比的能力对于各种应用，特别是生物矿化和晶体工程领域是重要的。拉曼光谱和粉末X-射线衍射被用来定量测定碳酸钙的二元和三元混合物的多晶型组成。结果发现，粉末X射线衍射的定量检测限上级拉曼光谱和红外光谱。
The ability to determine the calcium carbonate polymorphic ratio of calcite, aragonite and vaterite in a mixture is important for a variety of applications, particularly the fields of biomineralisation and crystal engineering. Raman spectroscopy and powder X-ray diffraction were used to quantitatively determine the polymorphic composition of both binary and tertiary mixtures of calcium carbonate. It was found that the quantitative detection limits of powder X-ray diffraction were superior to both Raman and infrared spectroscopy.
