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,

2009
Catalyst WO3/ZrO2 has been proved to have a high efficience in the benzoylation of anizole by benzoic anhydrite at 140 ??C. The results on benzoylation of toluene at 100 ??C and at different values of BA volumetric feed rate have been presented.
