Keywords

Abstract

The work is devoted to studying of Si⁴⁺+Mg²⁺ complex additive for obtaining transparent YAG:Sm³⁺ ceramics. The processes of densification of the YAG:Si⁴⁺,Mg²⁺ model system, which provides control of solid-state sintering processes due to changes in the concentration of defects in both the anionic and cationic sublattice, were studied. The best result in terms of optical quality (T = 84%) was achieved with YAG:Sm³⁺ (3 at.%) ceramics doped with 0.071 at% of Si⁴⁺ ions and 0.044 at% of Mg²⁺ ions.
