Abstract: The gelcasting process for shaping nano-sized Y-TZP was studied. The effect of organicmonomer and binder on the rheological properties of slurry was investigated. There existed the optimum amount of monomer, binder and initiator. Compared to dry pressing and isostatic pressingmethods, the specimens formed by gelcasting had higher density, more homogenous microstructureand higher fracture toughness.

Key words: gelcasting, nano-sized powder, Y-TZP
