The Fabrication and Characterization Behavior of Cordierite Ceramic Materials with different Molar Fraction

The investigation was concentrated on preparation of bioactive pure cordierite ceramic and evaluate the phase transformation which excepted to form during sintering process. Cordierite prepare by chemical co precipitation, integrated Cordierite gel with water-based sol–gel which begin essentially from Alumina Al2O3, magnesium oxide MgO and silicon oxide SiO2. Different specimens were fabricated with various weight percentage of Al2O3, Mgo and SiO2 powders. All specimens were prepared in cylindrical shape by using hydraulic press at pressure of 4 bar with holding time at this pressure for 30 minutes. Firing presses achieve at 10000C and 12500C with 2 hour holding time. The characterization of microstructure has been done by using Field Emission Scanning Electron Microscope (FESEM), which revealed homogenous distribution of the compounds with few porosities. The x-ray diffraction for phase transformation which occur during sintering process. The structure analysis of specimens shows at 1250°C cordierite phase form, also the results are shown formation of cristobalite, spinel, protoestatite and corundum with cordierite phase.
