The correct answer is:
Number of ions = n
Number of tetrahedral voids = 2n
Number of octahedral voids = n
Number of Y ions ,
Number of X ions
Occupied octahedral voids
So fraction of occupied octahedral voids .
Number of tetrahedral voids = 2n
Number of octahedral voids = n
Number of Y ions ,
Number of X ions
Occupied octahedral voids
So fraction of occupied octahedral voids .
