Notes:
The conversion of a Sr–Ti bimetallic methoxyethoxide precursor into SrTiO3 via hydrolysis and/or calcination was investigated. Hydrolysis with various water/metal molar ratios (rH; rH= 0.5, 2, 4, 6, 8, 10) in tetrahydrofuran at reflux resulted in a decrease in the amount of the methoxyethoxyl groups, and the hydrolyzed products were soluble with rH≤ 2. At rH≥ 8, SrTiO3 was crystallized without calcination. Both the hydrolyzed and unhydrolyzed precursors (rH= 0, 0.5, 2) were calcined in dry air at 550°–800°C. SrTiO3 was crystallized on calcination at ≥550°C from amorphous materials with a considerable loss of carbon, which was present as both chars and carbonate ions.
