    Abstract:
    The structure of ZnO based transparent glass-ceramics prepared from glasses by controlled crystallization and of optical ceramics prepared by uniaxial recrystallization hot pressing and doped with rare-earth (RE) and transition metal (TM) ions are compared.Regions of structural inhomogeneity are formed in glasses during their casting, cooling and annealing. Their composition depends on the type and concentration of TM and RE ions and determines the difference in phase assemblage of glass-ceramics. In optical ceramics, RE ions do not enter the structure of ZnO crystals, but are located on their surface and form the RE2O3 phase. The RE2O3 fraction increases proportionally to the RE ion doping level. ZnO glass-ceramics and optical ceramics doped with TM and RE ions are multiphase materials.
