This study investigated the effects of CeO2 on structure and synthesis of boroaluminosilicate transparent glass ceramics containing CaF2 nanocrystals prepared through isothermal crystallization of the melt-quenched glasses with composition 54SiO2–10B2O3–13Al2O3–14Na2O–3ZnO–2Li2O–4CaF2 doped with 0–1.2 mol% CeO2. CeO2 in polyvalent states acting as network modifier leads to disruption of the silicate network and the conversion of [BO3] to [BO4] generating the nonlinear variations in crystallization, and thermodynamic and optical features. Glass transition temperature and the crystallization temperature decrease firstly and then increase with the increase of CeO2 content. Correspondingly, the size of CaF2 nanoscale crystals and the absorption coefficient of the glass ceramics are found to pass through a maximum and then decrease with increasing CeO2 addition. Increasing CeO2 concentration and elevating treating temperature lead to red-shift of absorption edge and transparency deterioration of glass ceramics.
