| Abstract Scope |
Transparent magnesium aluminate spinel (MgAl2O4) ceramic is a rugged window material that has excellent transmission from the UV to mid-wave IR. Traditional processing of spinel has required multi step processing using either vacuum sintering or hot pressing (HP) followed by hot isostatic pressing (HIP) to produce a fully dense body with the desired properties. Spark plasma sintering (SPS) has been shown to be a successful alternative to produce fully dense spinel samples with fewer steps and faster processing times. We will discuss some recent efforts to produce high quality spinel using SPS for use in IR window applications. Information on the microstructure, optical, and physical properties of the SPS spinel will be presented and compared with spinel produced using HP and HIP methods. |
