摘要: Transparent polycrystalline sintered ceramic of cubic crystal structure. The invention relates to the field technical and transparent ceramics structure for applications with increased mechanical stress, e.g., as protective or armoring ceramic. Provided are that combine a high transmission RIT>75% theoretical maximum value distinctly improved hardness. real in-line measured on 0.8 mm-thick polished plates light wavelength between 600 650 nm, an average grain size D in range 60 nm
