Transparent Tetragonal Zirconia Ceramics by Colloidal Processing of Nanoparticle Suspension
Original language description
Colloidal processing was applied to a commercial 5 vol% 3Y-ZrO2 nanosuspension with a particle size of 10-15 nm. The nanosuspension was concentrated by evaporation or by the newly developed method of osmotic dehydration. The viscosity and stability of concentrated suspensions were investigated. The concentrated nanosuspension prepared by osmotic dehydration was consolidated by centrifugation in non-porous moulds. The dried deposit had a relative density of 46% and pores ranged from 4 to 8 nm. This deposit was densified by pressureless presintering to closed porosity, followed by hot isostatic pressing in order to obtain transparent ceramics. After sintering, the tetragonal zirconia retained the nanocrystalline structure with an average grain size of 65nm and an in-line transmission of 25 % (at 633 nm wavelength and 0.5 mm plate thickness).
