Salt. Coloured scanning electron micrograph (SEM) of pure salt (BDH Analar sodium chloride) re- crystallised from distilled water. These salt crystals are built up from a cubic lattice of sodium and chloride ions. In the absence of impurities an exact cubic crystal form would be produced. This image shows that in practice this basic cube is usually disrupted by dislocations; these give rise to crystals with a variety of shapes,although they all retain the basic cubic symmetry.
