Abstract

Natural volcanic perlite was investigated with respect to its properties as component of composite systems considered for biomedical applications. Beside the overwhelming vitreous phase, (Na,K)AlSi3O8 anorthoclase crystallites were also identified in the structure of the investigated perlite. The electron paramagnetic resonance and energy dispersive X-ray spectroscopy highlighted the presence of iron impurities. The specific surface area and high magnification micrographs point out the porosity of the grains. The results obtained both by differential scanning calorimetry and infrared spectroscopy indicated that perlite is highly inert in simulated body fluid containing serum albumin..
