This book, entitled "Cristallographie pour classes préparatoires", is intended for second-year students in the Maths-Physique, Physique-Chimie and Technologie preparatory classes. The content of this book follows the official program of the Ministry of Higher Education and Scientific Research for preparatory classes. The first chapter covers the basics of crystallography, presenting the interaction of a polycrystalline powder with X-ray diffraction (Debye and Scherrer methods). The second chapter describes compact stacks: the cubic ABC type and the compact hexagonal AB type. Semi-compact (centered cubic) and non-compact (simple cubic) stacks are also described. In the third chapter, the different families of MX-type ionic crystals are explained in detail: CsCl, NaCl, ZnS (blende). The MX2 type: fluorite (CaF2) and antifluorite M2X (Na2O).Finally, the last chapter is devoted to covalent carbon crystals. Diamond carbon has cubic symmetry, while graphite has hexagonal symmetry. The clarity of the topics covered in this
