cordierite glass ceramic nanopowder has been produced with an accurate stoichiometric by utilizing bentonite, talc alumina and kaolin as raw materials and using thermal shock process 10000C and then The prepared specimens were thermally treated at 11000C, 12000C and 13000C for 2 h. In order to identify the phases, morphology, optical analysis and thermal analysis of the glass ceramics XRD, SEM, FTIR and DTA/TGA have been used. XRD and DTA/TGA results showed that α-cordierite has been formed above 1160oC and its quantity has been increased continuously with increasing sintering temperature to 1300oC. Also XRD and SEM results showed size and crystallization of α-cordierite increases with increasing temperature. The FTIR spectra reveals the presence of broad band vibrations due to Al-O, Si-O and Mg-O
Keywords: Bentonite, Thermal shock, Glass ceramic, Cordierite.
