Effect of MgO doping on the structure and optical properties of YAG transparent ceramics
Original language description
The paper studies the features of Mg2+ ions as sintering aid for reactive solid-state sintering of YAG transparent ceramics. Phase composition, microstructure and optical properties of YAG ceramics, doped by 0 divided by 0.15 wt.% MgO, were investigated. Solubility limit of Mg2+ ions in YAG crystal lattice was found to be in the range of 0.06 divided by 0.1 wt.% of MgO additive. Substitution mechanism of Mg2+ in ceramic YAG was identified by comparison of XRD data and ab initio calculation. It was shown that within the solubility limit Mg2+ ions most likely substitute Al3+ sites. Doping by MgO above solubility limit led to precipitation of spinel secondary phases. It was found that doping by Mg2+ ions increases concentration of oxygen vacancies in YAG lattice that effectively promote sintering. The optimal concentration range of MgO sintering aid that allow to achieve YAG transparent ceramics was defined as 0.03 divided by 0.06 wt.%.
