(3MgO.1.5Al 2O3.5SiO2). B2O3, P 2O5 and CaO was also added to decrease the melting and sintering temperature of cordierite. The glasses were pelletized and sintered from 850°C up to 1050°C. Phase compositions of both heat treated glass was quantified by X-ray powder diffraction data by the Rietveld method using TOPAS Ver 3 software. Result shows that about 60wt% of α cordierite has successfully crystallized at 850°C. Beside secondary phases (forsterite) which come from initial raw materials, phases from grinding media were also presents in the sample. The contamination was considered high since it has reacted with existence phases to form a new phase at higher temperature. Without any contamination from grinding it was expected to obtain more than 90wt% α cordierite using the same composition. 2011-05-25T03:03:23Z 2011-05-25T03:03:23Z 2011 Article Advanced Materials Research, vol.173, 2011, pages 190-195 1022-6680 http://www.scientific.net/AMR.173.190 http://hdl.handle.net/123456789/12091 en Trans Tech Publications, Switzerland.
