Abstract

Perovskite related oxides such as (Ba, Ca)(Fe, Co)O_3-δ, (Sr, Ca)(Fe, Co)O_3-δ and (Ba, Ca)(Fe, Mg)O_3-δ have been developed as safety materials for quick solidification of CO₂ at high temperatures. The CO₂ solidification properties and microstructures were investigated. Perovskite oxides (ABO₃) become active for CO₂ accommodation due to the lattice distortion produced by mixing different alkaline earth ions in site A and the mixed valence states by substitution of Fe ions by Cc and Mg ions in site B. The mechanism of rapid CO₂ accommodation was taken into consideration.
