Electrical characterization by impedance spectroscopy of Zn7Sb2O12 ceramic
Materials Research, 2003 Impedance spectroscopy technique was used to investigate the electric properties of Zn7Sb2O12, an electroceramic with inverse spinel type structure. The electric characterization of the Zn7Sb2O12 semiconducting ceramic was performed at temperature from ...

Magnesia–spinel microcomposites
Journal of the European Ceramic Society, 2004Abstract This study used a model system of fully dense high purity MgO, incorporating micron size spinel prepared by hot-pressing. Spinel powder was obtained from two sources: (i) 0.5 μm alumina powder was incorporated into MgO by in situ reaction, and (ii) preformed 3 μm spinel powder.

Publisher Summary This chapter discusses the crystal structure and mechanism for structural distortion of spinels. Spinels are materials that crystallize with a structure related to that of the mineral MgAl2O4, which is known as spinel. The gross features of the spinel structure may be most easily visualized as a nearly close-packed cubic array of ...
