PY - 2017 TI - Er:Yag Polycrystalline Ceramics: Use of SiO2 and B2O3 as Sintering Additives and its Effects on the Optical and Structural Properties JF - Revista Cubana de FĂ­sica; Vol 34 No 2 (2017) KW - N2 - The effects of SiO 2 and B 2 O 3 as sintering additives were investigated on the optical and structural properties of Er:YAG polycrystalline ceramics sintered without additional external pressure and in high vacuum. Best optical and structural properties were obtained doping the ceramics with 0.5% of SiO 2 and 0.17 wt% of SiO 2 , and 0.33 wt% of B 2 O 3 (B 3+ :Si 4+ = 2.0) respectively, the former being the one with better results. On the other hand, it is shown that through the addition of B 2 O 3 it is possible to reduce sintering temperature and to obtain good density values.
