Studies on the combined effects of titania and silicon carbide on the phase developments and properties of carbon-clay based ceramic composite

Effects of titania (TiO2) and silicon carbide (SiC) on phase development and physico-mechanical properties of mullite-carbon were investigated. Powdered clay, kaolinite and graphite of predetermined compositions were blended with additives using ball mill for 3 h at 60 rev/min. Samples were produced...
