Goldschmidt tolerance factor是什么

WebGoldschmidt (79), on the basis of geometric considerations, defined the tolerance limits of the size of ions through a tolerance factor t = (rA + rx)l 2 (rB + rx), where rA,rB, and rx are the radii of the respective ions t would be equal to one for the ideal cubic structure (Fig. 2). In fact, the perovskite structure exists in oxides only ... 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.
