Synthesis and oxygen transport properties of La0.2Sr0.8Fe1.xTixO3.(x = 0.2, 0.4) intended for syn-gas production
Original language description
Perovskites in the system La0.2Sr0.8Fe1-xTixO3-d exhibit high stability at severe reducing conditions and high temperatures. Due to favourable transport properties they are possible candidates both in oxygen permeation applications and anodes in SOFCs. Here we report the processing and oxygen transport properties of two different compositions: La0.2Sr0.8Fe1-xTixO3-d (x = 0.2, 0.4). Single phase powders were synthesized by both spray pyrolysis (SP) and solid state reaction (SSR). The resulting average particle sizes (BET) ranged from 140 nm (SP) to 1090 nm (SSR). Bar shaped samples were prepared by cold isostatic pressing and pressure less sintered between 1200 and 1250oC for 8-12 hours. Final sintered densities ranged from 97 (SSR) to 99% (SP) and grain size was less than 1.5 um. The average thermal expansion coefficients (TEC) varied in the range (13.8 - 14.6) .10-6K-1 at 300-600C and (21.3 - 28.9) .10-6K-1 at 600-800C. Surface exchange coefficients (kchem) and bulk diffusion coeffici
