What percentage of tetrahedral holes is occupied in diamond?
Compute the percentage void space per unit volume of unit cell in zinc-fluride structure. In zinc fluoride, anions occupy
fcc positions and half of the tetrahedral holes are occupied by cations.
In a normal spinel type structure, the oxide ions are arranged in ccp whereas 18 tetrahedral holes are occupied by Zn2+ ions and 50% of octahedral holes are occupied by Fe3+ ions. The formula of the compound is ?
