本文通过斜方晶系水溶性晶体CuCl2.2H2O的生长实验,得到了晶体聚集体,观察了结晶形貌,探讨了该晶体聚集体形貌中蕴含的结晶学规律,建立了该晶体在理想情况下的聚集体的结晶学模型。在该模型中,晶体生长方向为[001],发育晶面为(100)、(010)和(110),形成聚集体形貌时晶体结合的共格晶界分别为(012)与(0 10—1)、(103)与(120 1)和(112)与(991)或(113)与(13131)。试验观察验证了模型的正确性。
Aggregation patterns of CuCl2·2H2O had been obtained by crystal growth in solution.After the observation and analysis under optical microscope,basing on some basic law on crystallography and morphology,the crystallographic relationship between crystals in the aggregation pattern was analyzed and the crystallographic model of the aggregation patterns was built.According to the results,crystal grows along the direction of ,and developes crystal faces(100),(010)and(110).Co-lattice nets are(012) and(0 10— 1),(103) and(12— 0 1),(112) and(991) or(113) and(13— 13— 1).Comparing with the aggregation achieved in experiment,a aggregation model of CuCl2·2H2O was suggested in this paper.
