what is the distance bet'n 2 tetrahedral voids in ccp structure ???????
ans is
1. a/root 2
2.a/2
3.root3*a/2
4.all above
answer is 4

whta type of crystal defect is produced when NaCl is doped with MgCl2?
pls explain metal excess and metal deficiency defect again...or by a video...ASAP
why frenkel defect does not change the density of agcl crystals???
what is the difference between isomorphism and polymorphism pls explain with some examples too..
