The distribution in a mixed crystal A1-xBxC grown from an either (A, B)-rich or C-rich solution zone (e.g. travelling heater method or related techniques) is to be described by Pfann's zone melting function which depends on the segregation coefficient and a characteristic length. Using pseudobinary mole fractions x the characteristic length of the distribution function is not the actual length of the liquid solution zone but an effective zone length is to be regarded which may be considerably smaller or much bigger for C-rich or (A, B)-rich solutions zones, respectively.
