(Also, as in previous discussions, k and T represent Boltzmann's constant and the absolute temperature, respectively.) The factor 2 is present in the denominator of the exponential because two defects (a missing cation and an interstitial cation) are associated with each Frenkel defect. Similarly, for Schottky defects, in an AX-type compound, the equilibrium number (Ns) is a function of temperature as N, = N exp Qs ... (2) Where Qs represents the Schottky defect energy of formation. Example 1 Calculate the number of Schottky defects per cubic meter in potassium chloride at 500 °C The energy required to form each Schottky defect is 2.6 eV, while the density for KCI (at 500 °C) is 1.955 g/cm³.
