Synthesis of Mullite by the Pechini Method


Article Preview

In the past few years there is a considerable interest in the study and application of the mullite, due to its chemical, physical and mechanical properties, in which are correlated with the synthesis method used. Aiming to achieve better structural and morphological properties, many synthesis methods are being studied, in which the Pechini method is highlighted, which is today one of the most viable methods and successful technique used in the preparation of nanosized materials. Thus, this study proposes the production of mullite powders by the Pechini method. The influence of different routes of synthesis was investigated. The material was sintered at 1100oC/2h, 1200oC/2h and 1400/2h, and characterized by X ray diffraction (XRD) and thermal analysis (TG/DTG and DTA). The results showed that the synthesis route did not interfere in the formation of the formed phases, and the mullite for both routes, was formed from 1200oC.
