Sol-gel synthesis of barium titanate using barium carbonate with glacial acetic acid and butyl titanate monomer

Barium carbonate with glacial acetic acid and butyl titanate monomer (BTM) were used as Ba and Ti precursors to obtain sols and hard transparent gels at room temperature. After the calcination of the gels at various temperatures (25–1250°C) in air, the mixed Ba Ti powder was characterized by DTA/DTG...

Beschreibung
Zusammenfassung:	Barium carbonate with glacial acetic acid and butyl titanate monomer (BTM) were used as Ba and Ti precursors to obtain sols and hard transparent gels at room temperature. After the calcination of the gels at various temperatures (25–1250°C) in air, the mixed Ba Ti powder was characterized by DTA/DTG/TG, XRD and IR. The formation of tetragonal BaTiO 3 as a major phase was seen to occur around 550°C.
