Abstract
- We investigated the chemical reactivities of (La<subscript>0.7</subscript>Sr<subscript>0.2</subscript>-Ba<subscript>0.1</subscript>)ScO<subscript>3-δ</subscript> (LSBS) and LaScO<subscript>3</subscript> powders and Pt foil as functions of reaction temperature, T, oxygen partial pressure, P(O<subscript>2</subscript>), and reaction time, t. The LSBS powder showed a maximal Pt content of ca. 33 mg (ca. 3 wt%) under the conditions T = 1573 K, P(O<subscript>2</subscript>) = 0.21 atm (in air), and t = 10 h. Subsequent heat treatment at 1773K in air for 10 h resulted in the deposition of Pt fine particles (1.7 mg) on the LSBS powder and a weight gain of the Pt foil (4.3 mg). [ABSTRACT FROM AUTHOR]
