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:
