Abstract

To quantify residual porosity of the materials is important when analyzing their microstructure and functional performance. The problem becomes particularly urgent for functional (optical, laser) materials. A common way to solve it is to calculate the quantity and size of pores on the sample's cross-section. However, authors do not pay special attention to experimental data processing. Present work studies pore size distribution in 1–4 at% Nd3+:YAG transparent ceramics using experimental measurements of pore sizes determined from the cross-section. Suggested method enables one to evaluate residual porosity correctly.
