TRANSPARENT NANOCRYSTALLINE BULK ALUMINA OBTAINED AT 7.7 GPa AND 800 C

Transparent nanocrystalline bulk alumina obtained at 7.7 GPa and 800 C had an average grain size of about 150 nm and an in-line transmission of 71% for a wavelength of 640 nm and a thickness of 0.8 mm. This is thought to be the lowest temperature at which highly transparent alumina has been obtained...
