Hello,
I found near results as mentioned above, porosity in water with Archimedes methos about %40 but via mercury porosity enstrument method %32. Our seramic samples have 3,5 nm-10 micrometer). Is there any problem or I expalined as using your giving document here mercury porosity measure just enterance of the open porosity not whole inner pore size. Is it avalible to write like this explanation?
