ELECTRO-PHYSICAL PROPERTIES OF SUPER-THIN BASALT FIBERS ON THE BASIS OF ARMENIAN BASALT ROCKS BEFORE AND AFTER CHLORHYDRIC ACID TREATMENT

For the first time, electro-physical parameters of super-thin basalt fibers (STBF) on the basis of Armenian basalt rocks are measured before and after chlorhydric acid treatment. It is shown that specific resistance and dielectric parameters of super-thin basalt fibers change essentially after chlorhydric acid treatment. It is revealed from thermogravimetric and other investigations that the probable cause of the change is the increase in total amount of pores and modification of the share of pores of various sizes in STBF followed by the increase of absorption of water molecules from the ambient medium. It is shown, in particular, that the obtained results (in both alternating and constant fields) can be interpreted within the framework of dipole-relaxation mechanism of polarization of water molecules in STBF pores.
