Schottky defects bcoz equal no of cations and anions are not present in lattice, that's vay mass of sub. change and we know that 
density = mass
             volume
it shows in highly ionic compound and small difference in sizes of cations and anions having compounds. eg. NaCl, CsCl, KCl, KBr, AgBr.
