Abstract
The UT-3 thermochemical water-decomposition cycle requires Fe reactant pellets with high reactivity and long life. Properties of Fe reactant pellets prepared using ZrO2-Y2O3, ZrSiO4 or SiO2 + ZrO2 as support ma terials were compared. The pellets with ZrO2-Y2O3 showed the highest d ensity, hardness and content of Fe reactant, and kept a steady reactiv ity of 1.6- 1.8 x 10(3) mol (Fe3O4) m-3 (pellet) 1 during 30 reaction cycles. The pellets with ZrSiO4 support were porous and showed high co nversion.
