This study investigates sintering temperature impact on porous materials from waste glass, suggesting improved recycling methods.
The increasing volume of waste glass released into the environment underscores the critical role of material recycling, particularly glass recycling, in promoting sustainable development. A promising approach is the recycling of waste glass into porous materials. This study investigates the influence of sintering temperature on the properties of porous materials made from waste glass. The material samples were fabricated by adding liquid sodium silicate to glass powder at a glass powder/liquid sodium silicate ratio of 9/1. The optimal sintering temperature range for the porous material was determined through a heating microscope, revealing a suitable range of 770 oC to 830 oC. The sintered porous glass samples were determined by properties such as pore size distribution analysis, density, water absorption, and porosity measurements to evaluate the properties of the resulting product. Furthermore, the Fourier Transform Infrared Spectroscopy technique was employed to assess the functional group composition of the product. This research contributes to the search for effective waste glass recycling solutions while simultaneously producing porous materials with high application potential.
