The aim of the present study was to synthesize CaO·GeO2 nanocomposite poweders glasses. The sample were prepared to 1450°C°. To investigate the structure of the samples, Differential Thermal Analysis (DSC), X-ray diffraction and Fourier Transform Infrared (FTIR) spectroscopy were used. The main crystallising phase was found to be CaGe205 crystals. The molar ratio of Ge06/Ge04 groups increases with the CaO·GeO2 molar ratio. Furthermore, in order to study the potential antibacterial properties of the materials the Gram-negative (Escherichia coli) bacteria was used and the diameter of zone of inhibition was observed.
