DEVELOPMENT OF GLASS-CERAMICS BY CONTROLLED NUCLEATION AND CRYSTALLIZATION OF GLASS SAMPLES PRODUCED FROM LOCAL RAW MATERIALS

📄 Project Abstract

Glass-ceramic materials were produced by the process of controlled nucleation and crystallization of glass samples. The glass samples were produced using locally available raw materials. (Feldspar, Limestone and Magnesite). The raw materials were sourced from Matari (Kaduna State), Kalambaina (Sokoto State) and Tsakesimptah (Adamawa State). The raw materials and the resultant glass-ceramics were characterized using instrumental analytical techniques such as X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersion spectroscopy (EDS) to ascertained their chemical compositions, mineral phases present, surface morphologies and elemental distributions respectively to enable the researcher to determined their suitability in glass and glass-ceramics making while differential scanning calorimetry (DSC) was used to determine the glass transition temperatures (Tg) of the produced glasses.Each glass-ceramics was produced using two main steps: In the...
