Description
Mullite is a ceramic material with high technological applications. Its synthesis has been extensively studied due to their excellent properties. Thus, this paper proposes to obtain mullite by Pechini method. The amount of acid citric/metal cations in proportions of 3:1 and 1:1 were investigated in order to understand their influence in obtaining the mullite phase. The synthesized samples were characterized by X-ray diffraction (XRD) and thermal analysis (TG/DTG and DTA). The results showed that the ratio citric acid/metal cations influence on the formed phase with the mullite obtained only in proportion 1:1. With the increase of the ratio to 3:1 was observed the formation of the alumina layer. (author)
