Unformatted text preview: concentration of vacancies can be determined from: i. C v = N v /N= e ( -Qv/Rt ) 1. Nv= Number of vacant sites 2. N= Number of lattice sites 3. Qv= Energy to and from 1 mol of vacancies 4. R= Gas Constant 5. T= abs temp in kelvin ii. Near the melting point of conecentration of vacancies can be 0.1% 2. Intersititial Defect a. An extra atom is inserted into that is not usually a lattice point. Intersitial atoms are typically small and just “squeeze” in...
