Several approaches for materials residual porosity assessment are presented in this paper. Importance of development of accurate model is shown based on Al 2 O 3 –Ce:YAG and Al 2 O 3 –Ce:(Y,Gd)AG ceramic phosphors taken as model objects. The evaluated difference in the outcomes of different methods applied for estimating porosity has been shown to be as high as ∼40%. The obtained results become applicable to another types of inclusions within the studied volume of a material as in the models under consideration the main role is given to a geometrical perspective of the problem.
