WebAug 23, 2024 · Most of the ceramics are crystal structures. We use the general term lattice to describe the general packing of atoms. Lattices are the minimum size of expression of the crystalline structures. If you unite lots of lattices, you will obtain the general crystal structure of that material. WebIn metals and crystalline ceramics mechanical response is intimately tied to crystalline defects and to crystalline grain structure. Grain structure can be considered in the context of a composite structure or as a locus for crystalline defects and this will be discussed later. The formation and
