Crystal structure is the top priority in the course of "Foundation of Materials Science" and it is the basis for learning the later professional knowledge. However, this content is abstract as it require learners to have a strong spatial imagination. The three-dimensional (3D) space arrangement of ions/atoms is difficult to express by means of traditional 2D images. In this paper, the teaching of perovskite (CaTiO₃) structure is taken as an example. The 3D crystal structure model with good operability is established by using Diamond software and network database. This model can clearly and intuitively display the arrangement of atoms in the crystal structure. By changing the sampling mode of the cube and the central atom of the ligand to construct the crystal structure model at different positions, the crystal structure of the perovskite is comprehensively carried out by the coordinate method, the closest packing method and the polyhedron connection method. These 3D crystal structure models help to improve students' interest and efficiency in learning.
