MODERN METHODS FOR THE POROUS MATERIALS ANALYSIS. INVESTIGATION OF POROUS SILICON NANOPOWDERS USING OF CAPILLARY CONDENSATION METHOD

Various methods for studying the main porous materials parameters are considered and compared. The method of thermal desorption of nitrogen was applied for nano porous silicon powders; the peculiarities of its application are revealed. It is shown that most of the pores in the porous silicon correspond to the size less than 5 nm.
