TG/DTA-EGA-MS studies on titania precursors with low content of organics for porous thin films of TiO2

Two commercially available nanosized TiO2 colloids and their suspensions in Triton X-100 have been precipitated and dried carefully. The solids obtained have been studied up to 500°C by simultaneous thermogravimetric and differential thermal analysis (TG/DTA) coupled online with quadrupole mass spectrometer for analysis of evolved gases (EGA-MS) in flowing air, nitrogen and helium atmosphere in order to check and model pyrolytic processes taking place at elevated temperature ranges of porous TiO2 layer fabrication techniques.
