This work addresses the thermodynamic evaluation of different spinel-containing refractory castable compositions in contact with a basic steel ladle slag (CaO/SiO2 ~ 9). The main differences among the castable compositions ...

SpinelViz is an application for the visualization of the spinel group minerals in three dimensions. SpinelViz uses the spinel prism to display mineral composition datasets from different tectonic settings. The application ...

The spinel group minerals provide useful information regarding the geological environment in which the host rocks were formed, constituting excellent petrogenetic indicators, and guides in the search for mineral deposits ...

In this work, a synthesis method of coating with thin layers of MgAl2O4 or ZnAl2O4 over alpha-Al2O3 spheres were developed.The method consisted in the deposition of a primer of bohemite on the spheres, followed by the ...

Structural and electrical properties of ZnO varistors were investigated as a function of spinel composition. Six varistor mixtures differing only in chemical composition of spinel, were prepared by mixing separately ...

A pyrometallurgical route for the synthesis of magnesium aluminate spinel by thermal treatment of a mechanical mixture containing 29 wt% MgO (periclase) and 71 wt% Al2O3 (alumina) in chlorine atmosphere was developed and ...

In this article we present a concise report on our studies on the magnetic behavior and structural arrangements of the inverse spinel Zn7-xMxSb2O12 system (M = Ni, Co). Studies on the temperature dependence of the magnetization ...
