A class of oxide is a spinal , it consists of two types of metal ions with the oxide ions. Many of the ferrite have spinel type structures. They are magnetic materials used in telephones or memory loops in computers. Spinel type structures normal and inverse. it has the following structure.

Fraction of the total octahedral voids occupied will be

A

`(1)/(2)`

B

`(1)/(8)`

C

`(1)/(4)`

D

`(1)/(6)`

Text Solution

Verified by Experts

The correct Answer is:
A
Since total no. of voids =8
and total no. of octahedral voids =4(1 at Body centre `+(1)/(4)xx12` at Edge centres)
So fraction of octahedral voids occupied will be `=(4)/(8)=(1)/(2)`

A spinel is an important class of oxide consisting two types of metal ions withs the oxide ions arranged in ccp layers . The normal spinel has one -eight of the tetrahendral holes occupied by one type of metal ions and one- half of the octaherdral holes occupied by another type of metal ion. Such a spine is formed by Mg^(2+), Al^(3+) and O^(2-) . The netutrality of the crystal is benig maintained. Type of hole occupied by Al^(3+) ions is:
