Title: Nd{sup 3+}:Y{sub 3}Al{sub 5}O{sub 12} laser ceramics: Influence of the size of yttrium oxide particles on sintering

Abstract

The influence of the size of Y{sub 2}O{sub 3} powder particles on the structure formation and densification of Nd{sup 3+}:Y{sub 3}Al{sub 5}O{sub 12} laser ceramics has been studied. It is shown that the use of 50- and 100-nm yttrium oxide particles makes it possible to synthesize single-phase yttrium aluminum garnet at temperatures of 1200 and 1500°C, respectively, whereas in the case of 5000-nm yttrium oxide particles 2-h exposure at a temperature of 1500°C yields only 80 wt % of the Nd{sup 3+}:Y{sub 3}Al{sub 5}O{sub 12} phase. Bulk swelling of pressed samples during sintering of 2.94Y{sub 2}O{sub 3}-0.06Nd{sub 2}O{sub 3}-5Al{sub 2}O{sub 3} powders with the size ratio of the initial particles R(Al{sub 2}O{sub 3}/Y{sub 2}O{sub 3}) ∼ 5 is observed. The application of different-sized powders (R ∼ 2.5) provides quantitative ratios between phases in the 3Y{sub 2}O{sub 3}-5Al{sub 2}O{sub 3} system at which shrinkage in a temperature range of 20–1500°C is dominant. Laser ceramics 0–2 at % Nd{sup 3+}:Y{sub 3}Al{sub 5}O{sub 12} have been obtained by the solid-phase sintering of oxide powders (R ∼ 2.5). The slope efficiency for 1 at % Nd{sup 3+}:Y{sub 3}Al{sub 5}O{sub 12} laser ceramics is found to be 33%.
