在原子力显微镜（AFM）下分析在初始阶段与磷酸或磷酸盐反应的方解石表面。在各种条件下，将裂解的方解石浸入磷酸或磷酸氢二铵中。方解石在磷酸中溶解后，在方解石表面上观察到许多沿特定方向取向的凹坑。当方解石浸入磷酸氢二铵中时，在方解石表面上观察到反应产物，也在特定方向上排列。X射线衍射分析表明，这些产物是含碳酸盐的羟基磷灰石。(C)2004 Elsevier B.V.保留所有权利。
A calcite surface reacted with phosphoric acid or phosphate in the initial stage was analyzed under an atomic force microscopy (AFM). The cleaved calcite was immersed in phosphoric acid or diammonium hydrogenphosphate under various conditions. The calcite dissolved upon immersion in phosphoric acid and many pits, oriented in a particular direction, were observed on the calcite surface. When the calcite was immersed in diammonium hydrogenphosphate, reaction products, also aligned in a particular direction, were observed on the calcite surface. X-ray diffraction analysis revealed that these products are carbonate-containing hydroxyapatite. (C) 2004 Elsevier B.V. All rights reserved.
