A spinel is an important class of oxides...

A spinel is an important class of oxides consising of two types of metal ions with the oxide ions arranged in cop layers. The normal spinel has one-eigth of the tetrahedral holes occupied by one type of metal ion and one-half of the octahedral holes occupied by another type of metal ion. Such a spinel is formed by `Mg^(2+), A^(2+) and O^(2-)`.  The neutratrality of the crystal is maintained.

A spinel is an important class of oxides consisting of two types of metal ions with oxide ions arranged in CCP layers. The normal spinel has 1/8 th of the tetrahedral void occupied by one type of metal and one half of the octahedral voids occupied by another type of metal ions such a spinel is formed by Zn^(2+), Al^(3+) and O^(2-) with Zn^(2+) in tetrahedral void. Then the simplest formula of that spinel is Zn_(x)Al_(y)O_(z) then x + y + z is
