Resumo
Solution-combustion synthesis (SCS) of MZrO3 zirconates (M = Ca, Sr, Ba) in an open reactor with glycine as a fuel was studied both experimentally and theoretically. Calculated thermal effects of the above SCS reactions were found to reasonably agree with experiment. The measured thermal effects of SCS reactions (ΔTmax) as a function of fuel/oxidant ratio (φ) exhibited a maximum within the range φ = 0.9–1.3 arising due to increasingly growing radiative heat loss from the open surface of burning reactive mixture. The occurrence of self-sustained SCS reactions yielding CaZrO3, SrZrO3, and BaZrO3 was found possible for φ ≥ 0.4, 0.3, and 0.4, respectively.
