o The EHPS approach uses high pressures (up to 6 GPa) to retard bulk diffusion rates, break powder agglomerates, and reposition nanoparticles very close to each other to help eliminate porosity in the sintered ceramic. o NRL researchers then can exploit the increased surface potential of nanoparticles for surface-energy-driven densification without coarsening.Researchers develop harder ceramic for armor windows1Scientists find new toughening mechanism for ceramicso But in 2012, Nishiyama and co-
