Transparent Spinel Ceramic

NRL has developed a suite of processes to create transparent spinel (MgAl2O4) ceramic, which is superior to the glass, sapphire, and other materials traditionally used for applications such as high-energy laser windows and lightweight armor. Commonly-used vacuum hot presses are utilized to sinter spinel powder into transparent solid materials. The NRL method includes a novel spray-coating process to uniformly coat the spinel powder particles with a sintering aid.
