Our experiments on the recovery of the glass waste resulted from cathode ray tubes - CRT were focused to designing compositions of glass-ceramic from glass waste with possible applications in composite materials. The recipes were calculated using as much waste as possible, using various nucleating agents and varying percentages, showing in this study the influence of ZrO₂. The report of CRT glass used for the neck:funnel:panel components were 5:30:65%, identical to the ones in CRT. We determined the following physical and mechanical properties: density, porosity, absorption, thermal expansion, hydrolytic stability. In order to characterize in terms of compositional and microstructural, the analyses were carried out by X-ray diffraction and scanning electron microscopy measurements, showing the influence of the nucleating agent and thermal treatment temperature on the properties of the glass ceramics.
