Abstract
Characterization of the volcanic glass (perlite) from Bitola region (Republic of Macedonia) was performed by the chemical, XRPD, IR and SEM analyses. The chemical analysis shows that the volcanic glass (perlite) represents an acidic volcanic rock with high percentage of SiO2 (72.45%), high percentage of alkali metal oxides (4.21% K2O, 3.56 % Na2O), and loss on ignition 3.54%. Results of the XRPD analyses indicate the presence of the amorphous phase with small presence of crystalline phases (feldspars, quartz, cristobalite and magnetite). SEM examinations point to the glassy structure with presence of pores with 50-100 μm in size.
