The dopant ion substitutes Y3+ in the crystal, and despite low concentration it influences the sintering process. It has been shown for example that, differently to Yb, Nd fastens sintering, and this is related to the ionic radius. This work describes the influence of doping ions on the microstructure evolution of transparent YAG ceramics and on the material properties. Variously doped YAG ceramics have been prepared by solid state reaction under high vacuum and characterized in terms of microstructure and thermal and mechanical properties. A model relation approximating the optical transmittance is provided. Transmittance is then presented not only as a material characteristic, but also as an indicator of microstructure development. The sintering and densification is discussed in relation to the transmittance and to material properties, in all cases considering the effect of the doping ions. It is interesting to show the sensitivity of various properties on the microstructural homogeneity and the small differences in porosity lying between nearly dense, translucent and transparent material. The influence of the active ions on the sintering evolution and consequently final properties highlighted in the present work can be exploited for the\noptimization of the processing conditions."@en . @prefix modulo: . prodotto:ID296268 prodottidellaricerca:prodottoDi modulo:ID9384 . @prefix istituto: . prodotto:ID296268 prodottidellaricerca:prodottoDi istituto:CDS073 . @prefix unitaDiPersonaleEsterno: . prodotto:ID296268 pubblicazioni:autoreCNR unitaDiPersonaleEsterno:ID16059 . @prefix unitaDiPersonaleInterno: . prodotto:ID296268 pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA8446 . istituto:CDS073 prodottidellaricerca:prodotto prodotto:ID296268 . unitaDiPersonaleInterno:MATRICOLA8446 pubblicazioni:autoreCNRDi prodotto:ID296268 . unitaDiPersonaleEsterno:ID16059 pubblicazioni:autoreCNRDi prodotto:ID296268 . modulo:ID9384 prodottidellaricerca:prodotto prodotto:ID296268 .
