Crystallography classes
WebFor non-crystallographers, who make up the vast majority of students in crystallography classes, some half a dozen suitably chosen patterns, if extensively dealt with, should normally be adequate to develop some desirable skill in recognising a space group and to convey a sufficient understanding of the subject for practical purposes. WebThe "building block" of a crystal, which is called the Bravais lattice, dtermines some of the physical properties of a material. An understanding of these crystallographic principles will be vital to discussions of defects and diffusion, which are covered in the next module. 3.16 Crystals with 2 Atoms per Lattice Point 6:24
