Worm‐like calcite crystals were successfully synthesized by hydrothermal method in heavy alkylbenzene sulfonate (HABS)‐ silicate hybrid aqueous system at 45 °C for 48 h. The result indicated that HABS can affect step/kink sites on the growth face of {104} calcite by alternating Ca²⁺ or CO₃²⁻ layers, resulting a slight rotation or stacking faults of the subunits, which lead to the worm shape of crystalline aggregates by elongating parallel to the c‐axis of the rhombohedral lattice. The overlapping worm structures were obtained with the synergistic effect of HABS and silicate, which presents an additives‐mediated crystallographically self‐assembly of worm‐like units and also the inheritance of orientated attachment with rhombohedral calcite habits.

HABS硅酸盐通过定向附着物控制蠕虫状方解石的合成

在重烷基苯磺酸盐（HABS）-硅酸盐杂化水体系中，在45°C下水热法成功地合成了蠕虫状方解石晶体。结果表明，HABS可以通过交替的Ca ²⁺或CO ₃^2-层影响{104}方解石生长面上的台阶/扭结部位，导致亚基的轻微旋转或堆积缺陷，从而导致蠕虫状通过平行于菱面体晶格的c轴延伸而形成结晶聚集体。重叠的蠕虫结构是在HABS和硅酸盐的协同作用下获得的，这表现出添加剂介导的蠕虫状单元的晶体学自组装，以及具有菱形方解石习性的定向附着的遗传。
