Effect of sintering temperatures on the physical, structural properties and microstructure of mullite-based ceramics

This study explored the impact of sintering temperature variations on the synthesis and characteristics of mullite ceramics derived from a composite blend of kaolinite clay, silica (silicon dioxide), and feldspar. Sintering temperatures ranging from 1100 to 1200 °C were systematically examined to an...
