Question

in normal spinel structure there is a closed packed array of o2 ions the trivalent cation are present in

Answer 1

Hey Mate here is your ans
=>In normal spinel structure there is a closed packed array of O2– ions. The trivalent cations are present in:-


(1) 75% of octahedral voids
(2) 50% of octahedral voids
(3) 12.5% of tetrahedral voids
(4) 25% of octahedral void

Answer 2

Answer: 50% of O.V.

Explanation:

In normal spinal str. X2+ occupy 1/8th of the tetrahedral voids and Y3+ occupy 1/2.

I.e. 50% of O.V.
