2013
Variation of fracture toughness KIc of ZrO2- Y2O3 ceramics (density ~ 98%) was studied depending on both testing machine traverse speed (0.005-50 mm/min) and preloading under KI < KIc conditions. It was demonstrated that within a strain-rate range from 0.05 to 5 mm/min fracture toughness practically does not change.

Iron species in FeOx/ZrO2 and FeOx/sulphated-ZrO2 catalysts

2005
Iron containing catalysts were prepared by (i) impregnation of ZrO2 with aqueous solutions of Fe(NO3)3, Fe/Zi, or aqueous solutions of NH4Fe(SO4)2, FeS/Z; (ii) chemical vapour deposition of FeCl3 on ZrO2, Fe/ZCVD; and (iii) impregnation of sulphated-ZrO2 with toluene solutions of Fe(acetylacetonate)3, Fe/SZ. After drying at 383 K and calcining at 823 K,
