Abstract

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.
Nd3+: YAG和Sm3+: Y2O3透明陶瓷制备的初步研究
本文对透明多晶陶瓷的制备进行了初步研究。采用固相反应制备了钐掺杂氧化钇(1%、3%和5%)和钕掺杂YAG (Y3Al5O12)半透明陶瓷。Sm3+: Y2O3采用Sm2O3 (6μm)和Y2O2 (20 ~ 50 nm)作为起始材料,Nd3+: YAG采用α-Al2O3、Y2O3和Nd2O3 (20 ~ 50 nm)作为起始材料。制备Nd3+: YAG时,以0.5 wt%正硅酸四乙酯(TEOS)为烧结添加剂,1 wt%聚乙二醇-400为分散剂。
