In this paper, the sol-gel synthesis and characteristic properties of kalsilite-type alumosilicates (KAlSiO4 and K0.5Na0.5AlSiO4) are reported. The polycrystalline powders were characterized by thermal analysis (TG/DTA), powder X-ray diffraction analysis (XRD), IR spectroscopy and scanning electron microscopy (SEM). Single-phase kalsilite oxides have been obtained after annealing precursor gels for 5 h at 750 degrees C. It was demonstrated that crystallinity of the samples slightly depends on the duration of annealing. From the results obtained, it could be concluded that the KAlSiO4 solids are composed of the volumetric plate-like grains grains with no regular size (from 5 mu m to 30 mu m). Larger crystallites for mixed potassium-sodium kalsilite have formed (from 10 mu m to 80 mu m) in comparison with potassium kalsilite samples.
