Transparent Tetragonal Yttria-Stabilized Zirconia Ceramic: Influence of Scattering Caused by Birefringence

Original language description

The correlation between grain size, optical birefringence, and transparency is discussed for tetragonal zirconia (ZrO(2)) ceramics using the Mie, Rayleigh, and Rayleigh-Gans-Debye scattering models. Our results demonstrate that at the degree of mean birefringence in the range (0.03-0.04) expected for tetragonal ZrO(2), only the Mie theory provides reasonable results. At small particle size (< 50 nm) the more straightforward Rayleigh approximation correlates with the Mie model. A real in-line transmission of similar to 50% at visible light and 1 mm thickness is expected at a mean grain size < 40 nm and similar to 70% at a mean grain size < 20 nm. At an infrared (IR) wavelength of 5 um there should not be any scattering caused by birefringence for grainsizes < 200 nm. Our simulations were validated with experimental data for tetragonal ZrO(2) (3 mol% Y(2)O(3)) ceramics made from a powder with an initial particle size of similar to 10 nm by sintering in air and using hot-isostatic pressi
