[Closed cell rate]: the closed cell rate is defined as the ratio of the closed cell volume of the sample to the apparent volume (visible volume) of the sample, that is, the closed cell rate=A0/Aa, where: A0 -- the volume occupied by the closed cell (m3); Aa -- apparent volume of the sample (visible volume) (m3). For the closed porosity, the density of the material itself must be known.
