Comparative analysis of selected silica – rich solid wastes for potential application as silica source in silica based ceramic products

The goal of this research is to characterize selected silica-rich solid wastes for potential use as silica source. two prominent chosen study are waste container soda-lime glasses and rice husks (agro-waste), both which known be wastes. Rice husk ashes (RHAs) were produced by thermally treating husks, while soda-lime-silica (WSLSG) crushed milled produce glass powder. EDXRF was used examine the chemical compositions, XRD determine mineralogical composition. SEM morphology these wastes; TGA/DTA evaluate their thermal behavior; FTIR molecular bonding. results revealed that RHAs WSLSG contain similar oxides but have a higher SiO2 content 79.7 69.4 wt. percent respectively. show typical amorphous band; Si - O- (SiO2) bonding at intense wavelengths 1069.7 cm-1 939.3 cm-1, respectively, weak 797.7 767.8 microstructure analysis irregular geometry, fewer pores. According results, better stability with temperature.
