| Abstract | The influence of Cu2O addition on crystallization process and microstructure of the transparent mica glass-ceramics was investigated. Cu+ ions which were added as Cu2O were oxidized to Cu2+ ions during preparation of parent glasses and the Cu2+ ions were reduced to Cu+ ions again during heating of the parent glasses. By heating the parent glasses to which 10-20 mol% Cu2O was added at 650-700°C, not only nanosized micas but also Cu2O nanoparticles separeted. Their separation temperatures were lowered as the additive amount of Cu2O increased. Micas separated at 750°C should contain Cu+ and Cu2+ ions in the structure. Metallic Cu was observed only in the specimen to which 1 mol% Cu2O was added. |
