Abstract: 

Correlation between the in-line optical transmittance and residual porosity of Y2O3 nanoceramics formed by high-pressure low-temperature sintering has been established. In the limit case, when the pore diameter is much smaller than the wavelength a formula for estimating the porosity at the known value of linear transmittance was obtained. For investigated samples of nanograin composite ceramics with average grain size of 10–20 nm, the pore size of 12 nm and linear transmittance of 50 % at wavelength of 900 nm the calculated value of residual porosity was 0.27 %. Phase composition of Y2O3 nanoceramics may be taken into account by varying refractive index of the composite ceramics containing both cubic and monoclinic yttria.
