Tetragonal Spinels

Distortions from cubic to tetragonal symmetry are commonly encountered in spinels. These distortions require the introduction of [Pg.143]

T ) ion in presece of Mn ( J - T ) ion on the structure of spinel lattice. The compounds with x = 0, 0.2, 0.4, 0.6 and 0.8 showed cubic structure while spinel with x = 1 showed tetragonal spinel phase. Electrical resistivity as well as thermoelectric measurements showed above spinels to be p-type semiconductors. The catalytic behaviour of spinels prepared was investigted for decomposition of hydrogen peroxide. [Pg.507]
