Impurity defects in solids
WitrynaInterstitial defects are atoms that occupy a site in the crystal structure at which there is usually not an atom. They are generally high energy configurations. Small atoms (mostly impurities) in some crystals can occupy interstices without high energy, such as hydrogen in palladium. Witryna27 sie 2024 · 1. A method of introducing defects in ionic solids by adding impurity ions. 2. If the impurity ions are in different valence state from that of host, vaccancies are creited in the crystal lattice of the host. 3. For cg., addition of CdCl2 to silver chloride yields solid solutions where the divalent cation Cd2+ occupies the position of Ag2+ 4.
