Phase Equilibria in the 1375°C Isotherm of the System Sr‐Ti‐O
Source abstract
Abstract
The phase relations in a portion of the 1375° isotherm of the system Sr‐Ti‐O were determined. The following ternary phases were identified: Sr 2 TiO 4 , Sr 3 Ti 2 O 7 , Sr 4 Ti 3 O 10 , SrTiO 3 (ss), and what is believed to be SrTi 12 O 19 . The experimental techniques used in the determination of tha phase diagram are somewhat uncommon and are discussed in depth. Diffuse reflectance spectra were obtained for several compositions of SrTiO 3 (ss). The broad absorption maximum shown in these spectra is attributed to Ti 3+ .
