AbstractAbstract
[en] The determination of porosity is connected with difficulties due to the various kinds and shapes of the pores as well as their wide range of sizes. The assumptions which must be made for the calculation of the pore diameters are sometimes rough approximations compared with reality. For some purposes, it is necessary to know the open porosity or pore size distribution, in other cases the total porosity may be of interest. To meet the particular requirements, a series of methods have been developed. They will be shortly described and the reasons for the limitation of their application are listed up in the tables containing advantages and disadvantages of the particular procedures. (orig./IHOE)

Im folgenden wird in kurzer Form ueber eine Reihe von Messverfahren berichtet, die zur Bestimmung der Porositaet und der Porengroessenverteilung verwendet werden. Sie weisen alle gewisse Vorzuege, aber auch Nachteile auf, die sich aus den Unterschieden in Art und Form sowie aus den sehr weiten Groessenbereichen der Poren ergeben. (orig./IHOE)Primary Subject
