Paper Abstract

Spinel ceramic exhibits excellent optical and mechanical properties, but its widespread use in high volume applications has been limited primarily due to the high cost associated with hot pressing and finishing. While, we have previously demonstrated techniques to reduce finishing costs, in this paper we report on the use of microwave sintering to make spinel ceramic at significantly lower cost than traditional hot pressing. We also identify preferred grain growth as well as an intra-granular fracture mode.
