NORMAL SPINEL (AB2O4 )
STRUCTURE:
Example of Spinel is a MgAl2O4.( mineral) In it oxide ions (O-2) are arranged in ccp with Mg+2 ions occupying tetrahedral voids and Al+3 ions in a set of octahedral voids.
Many ferrites (such as ZnFe2O4) also possess spinel structure. These are very
important magnetic materials and are used in telephone and memory loops in
computers.
