应用Ｄ／ｍａｘ－ⅢＣ型全自动Ｘ射线衍射仪对常温下几种化学合成的ＣａＣＯ３结构进行了研究．结果表明，一般化学法合成的ＣａＣＯ３以方解石结构存在；在液晶相中合成的ＣａＣＯ３以霰石结构存在；而在用超声处理过的液晶相中合成的ＣａＣＯ３既有方解石结构存在，又有霰石结构存在
Application of D / max-ⅢC automatic X-ray diffraction instrument at room temperature several chemical synthesis of CaCO3 structure were studied. The results show that the CaCO3 synthesized by the general chemical method exists in the calcite structure; the CaCO3 synthesized in the liquid crystal phase exists in the form of aragonite; while the CaCO3 synthesized in the sonicated liquid crystal phase has both the calcite structure and the aragonite structure
