摘要：

Computer simulation techniques have been used to predict the crystal morphology of the spinel ZnCr2O4. In agreement with experiment, crystallites are predicted to be essentially octahedral with the {111} surface dominating the structure. However, surfaces for materials with the spinel structure are highly complex and stabilized only by the formation of surface defects. This leads to a large number of different possible surface structures.
