Why does Frenkel defect not change the density of AgCl crystal?
In the frenkel defect the ions are not removed from the crystal to maintain electrical neutrality. so there will be no change in the crystal structure. that is there is no decrease in the no of ions.all the ions are inside the crystal.they are only dislocated.
What is the difference between ferromagnetic and ferrimagnetic substances?
