Green synthesis of calcium magnesium silicate using industrial waste material

The aim of this work can be summarized by the catchy-phrase “waste to wealth”. This research will develop environmentally friendly and cost-effective ceramic materials from industrial waste streams. The idea is to provide ways to utilize recycled industrial material for the production of calcium magnesium silicate (CMS) materials. In this way, instead of landfilling, waste can be recycled into value-added products. The waste-to-value-added ceramics conversion not only resolve the disposal problems but also conserves natural resources. In this work, we used a modified sol–gel method to convert fly ash (FA) and ground granulated blast furnace slag (GGBS) a low cost, abundant industrial waste, into highly-demand CMS. The structure optimization was done by treating the initial precursor with the different molar concentrations (2 M, 3 M, and 4 M) of solvents. The X-ray diffraction (XRD) studies and Fourier transform infrared (FTIR) spectroscopy analysis confirm the formation of CMS. The UV–Vis study reveals that the prepared materials exhibit a band gap in between 3.3 and 3.5 eV. These studies showed that the prepared material CMS can be used as host matrix in luminescence applications.
