Zinc aluminate (ZnAl2O4), naturally occurring as the mineral gahnite, is a member of the spinel family. At present zinc aluminate is used as a catalyst for the dehydration of saturated alcohols to olefins, methanol and higher alcohol synthesis, preparation of polymethylbenzenes, synthesis of styrenes from acetophenons, and double bond isomerisation of alkenes. Furthermore, zinc aluminate can also be used as a catalyst support, since it has a high thermal stability, low acidity and a hydrophobic behavior. In this study, we fabricated dense ZnAl2O4 using Spark Plasma Sintering (SPS) at 1200℃. Through the XRD analysis, we identify ZnAl2O4 of the single phase. Also Optical, physical properties and microstructure were measured.
