Abstract:
Zirconia dental ceramics exhibiting opalescence and having a grain size in the range of 10 nm to 300 nm, a density of at least 99.5% of theoretical density, a visible light transmittance at or higher than 45% at 560 nm, and a strength of at least 800 MPa.

Claim (Index 4):
A method of manufacturing an opalescent zirconia dental article comprising:\n providing a well-dispersed suspension of zirconia nanoparticles having an average particle size of less than 20 nm; forming the suspension into a shape of the dental article or a blank to produce a wet zirconia green body; drying the wet green body in a controlled humidity atmosphere to produce a zirconia green body; heating the zirconia green body to provide a zirconia brown body, wherein the zirconia green body is shaped before heating, or the zirconia brown body is shaped after heating; sintering the zirconia brown body at a temperature below or equal to 1200\u00b0 C. to provide an opalescent zirconia sintered body; wherein a resulting grain size of the sintered dental article is between 10 and 300 nm and an average grain size is between 40 nm and 150 nm.
