Goldschmidt's tolerance factor (from the German word Toleranzfaktor) is an indicator for the stability and distortion of crystal structures. It was originally only used to describe the perovskite ABO3 structure, but now tolerance factors are also used for ilmenite. Alternatively the tolerance factor can be used to calculate the compatibility of an ion with a crystal structure. WebGoldschmidt [ 9] defined the tolerance factor ( t) to account for the limits of the size of the cations to form a perovskite structure as. For complex perovskites of the type A (B’ 1/2 B” 1/2 )O 3, the above equation can be modified as. In general when the value of t is close to 1, the perovskite phase will be formed.
