Abstract
Structure and crystallization of K 2 O·TiO 2 ·3GeO 2 glass have been investigated by means of Fourier transform infrared spectroscopy (FTIR), differential thermal analysis (DTA), differential scanning calorimetry (DSC), x-ray diffraction analysis (XRD), and scanning electron microscopy (SEM). XRD analysis of crystallized glass reveals the presence of crystalline K 2 O TiO 2 3GeO 2 indicating the same composition of crystalline and parent glass. For glass particle size > 0.15 mm volume crystallization is dominant crystallization mechanism. SEM investigation of the crystallized glass confirmed volume crystallization of spherical nuclei.
Struktura a vlastnosti K2O·TiO2·3GeO2 skel byly zkoumány infraèervenou spektrometrií s Fourierovou transformací (FTIR), diferenèní termickou analýzou (DTA), diferenèní skenovací kalorimetrií (DSC), RTG difrakèní analýzou (XRD) a skenovací elektronovou mikroskopií (SEM). RTG analýza zkrystalovaných skel odhalila pøítomnost krystalického K2O·TiO2·3GeO2 ukazující totožné složení krystalické a skelné fáze. Dominujícím mechanismem krystalizace èástic skla vìtších než 0,15 mm je objemová krystalizace sférických nukleí, která byla rovnìž potvrzena SEM analýzou.
