Aluminum titanate was prepared by two different methods. A monophasic gel was obtained by cohydrolysis and polycondensation reactions of chelated aluminum sec‐butoxide and titanium isopropoxide. A diphasic gel was obtained from boehmite and anatase. Effects of homogeneous dispersion of magnesium oxide and iron oxide incorporated as alkoxides in the monophasic gel and also the effects of isostructural seed on the crystallization and densification of aluminum titanate obtained from monophasic and diphasic gels were investigated. Seed particles of MgTi2O5 facilitated lowering of crystallization temperature and enhanced densification of aluminum titanate. Microstructure studies indicated that almost‐microcrack‐free sintered bodies with smaller grains were formed from the seeded monophasic and diphasic gels.
