Polarised light micrograph of crystals of salt (sodium chloride). Salt crystals are built up from a cubic lattice of sodium and chlorine ions. In the absence of impurities an exact cubic crystal is formed. In practice the basic cube is often disrupted by dislocations,giving rise to crystals with a variety of shapes,although they retain the underlying cubic symmetry. Magnification unknown | |
