粉末X射线衍射内标法研究丙酮溶液中β-HMX的晶习
The Crystal Habit of HMX in Acetone Solution: An Internal Standard Powder X-ray Diffraction Study
摘要
Abstract
To explore the crystal habits of β-HMX in acetone,we prepared β-HMX single crystals by solvent evaporation method and applied powder X-ray diffractions to determine all the crystal surfaces,using powder GeO2 as the internal standard sample for the refinement and the zero shift correction.A model was established for the crystal habit ofβ-HMX in acetone and compared to those reported in literature.The crystal surface ofβ-HMX are indexed as (1 0 0),(0 1 1),(-1 1 1) and (0 2 0).Among them,the (1 0 0) crystal face is the largest one,following by (1 1 0) and (-1 1 1) and (0 2 0),which consists with the theoretical calculated AE model with solvent effect correction.Because of the weak interactions with acetone molecules,(1 1 0) and (0 2 0) crystal faces disappeared gradually during the crystal growth process,which indicates the solvent environment has significant effect on the morphology of β-HMX.关键词
