本文在前人研究的基础上，对方解石的解理性质、表面（自由）能、表面松弛度、润湿性和吸附行为等各向异性物理化学性质进行了综述。讨论了这些表面性质之间的关系。分析表明，方解石表面断裂键密度与表面能之间存在正相关关系，前者可用于预测解理性质、常见暴露面和表面松弛程度。表面Ca原子的分布特征和断裂（或不饱和）键的数目可以用来解释方解石的各向异性表面润湿和吸附行为。表面断裂键是研究矿物和材料表面性质的一种快速方法。(C)2017由Elsevier B.V.出版
The anisotropic physicochemical properties of calcite, including cleavage nature, surface (free) energy, surface relaxation degree, wettability and adsorption behaviour, were revisited in this paper based on the surface structures and surface broken bonds reported previously. The relationships between these surface properties were also discussed. The analysis indicated that the positive relationship between the density of surface broken bonds and the surface energy of calcite was established, and the former could be used to predict the cleavage nature, commonly exposed surfaces and the degree of surface relaxation. The distribution characteristic and the number of broken (or unsaturated) bonds of surface Ca atoms can be used to explain the anisotropic surface wetting and adsorption behaviour of calcite. This review demonstrated that surface broken bonds could be a fast way to study the surface properties of minerals and materials. (C) 2017 Published by Elsevier B.V.
