Abstract
In the present work we present preliminary research on producing of
transparent polycrystalline ceramics. Samarium doped Yttrium oxide
(1%, 3% and 5%) and Neodymium (1%) doped YAG (Y3Al5O12)
translucent ceramics were fabricated by solid-state reaction. Commercial
nanopowders was used as the starting materials: Sm2O3 (6µm) and Y2O2
(20-50 nm) for Sm3+: Y2O3 and α-Al2O3, Y2O3 and Nd2O3 (20- 50 nm)
for Nd3+: YAG. For the preparation of Nd3+: YAG, 0.5 wt% tetraethyl
orthosilicate (TEOS) was use as sintering additive, and 1 wt % PEG
(polyethylene glycol-400) as dispersant.
