The spinel structure consists of an array of 0 ions in fcc arrangement General formula of spinel is AB 04 Cations of A occupy 1 8 th of the tetrahedral voids and cations of B occupy half of the octahedral voids Spinels are always electrically neutral and these are important class of compounds There are also inverse spinels in which the distribution is B AB 04 Those in square brackets denote the species in octahedral voids Question 18 Which of the following is an inverse spinel Options a PbFe 04 b ZnO Al O3 c Fe304 d Mg0 Al O3
