Properties of powders of fused spinels and periclase pulverized by different techniques

Properties of powders of fused spinels and periclase pulverized by different techniques The properties of electrofused spinel and periclase powders prepared by different milling techniques are reported. Vibratory milled specimens display a higher structure imperfection of the surface, and the amorphous surface layer differs compositionally from the percursor material. In the pulverized products, contaminating elements (Na, Si, and, to a lesser extent, Fe) tend to migrate towards the surface of particles. Vibro-milled powders show a better sinterability in comparison to jet-milled powders. Pulverization produces little effect on the properties of precursor fused periclase. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

The properties of electrofused spinel and periclase powders prepared by different milling techniques are reported. Vibratory milled specimens display a higher structure imperfection of the surface, and the amorphous surface layer differs compositionally from the percursor material. In the pulverized products, contaminating elements (Na, Si, and, to a lesser extent, Fe) tend to migrate towards the surface of particles. Vibro-milled powders show a better sinterability in comparison to jet-milled powders. Pulverization produces little effect on the properties of precursor fused periclase.
