Fabrication of transparent yttria ceramics by alcoholic slip-casting
Source abstract
Abstract
Abstract Y 2 O 3 transparent ceramics were prepared from alcoholic slurries of Y 2 O 3 nanopowders via a slip-casting method to avoid the hydrolysis issue. Polyvinyl pyrrolidone (PVP), polyethylene glycol (PEG) and polyethylenimine (PEI) were used as dispersants to improve the rheological properties of the slurries. It was found that PEI is the most effective dispersant in ethanol. The adsorbed amount of PEI was evaluated by infrared absorption and rheology measurements. Y 2 O 3 slurry with a solid loading of 20.8 vol% and a viscosity of −1 was obtained using 1.5 wt% PEI. The slurry yielded a homogeneous green body, and finally resulted in a high-quality Y 2 O 3 ceramic with the in-line transmittance of 80% at 800 nm.
