Abstract Scope Transparent magnesium aluminate spinel (MgAl2O4) ceramic is a candidate rugged window material due to its mechanical properties and wide IR transmission. In this paper, we report the fabrication of highly transparent spinel ceramics using a microwave sintering technique. Microwave sintering offers various advantages over conventional densification methods due to its capability of rapid and uniform heating, shorter sintering time, lower sintering temperatures, scalability, and finer microstructure of the ceramics. Highly transparent and homogeneous ceramics have been obtained using commercial spinel powder by this method. The optical, spectral and morphological properties from highly transparent ceramics are presented.
