Phase equilibrium in ternary system Li3PO4–Na3PO4–InPO4 and formation of heterovalent Zr‐substituted solid solutions (up to 15 mol%) for In3+ in Li3In2(PO4)3 and Na3In2(PO4)3 complex phosphates were studied by the cross‐section method at 950°C. Samples obtained were investigated by X‐ray powder diffraction and impedance spectroscopy. Ionic conductivity of Na3In2(PO4)3 and Li3In2(PO4)3 complex phosphates is about 10−2 S/cm at 300°C. Heterovalent substitution was performed according to the scheme: In3+=Zr4++v, where v is a vacancy in cationic sublattice. Zr‐substituted (15 mol%) Na3In2(PO4)3 and Li3In2(PO4)3 have ionic conductivity of about 10−1 S/cm at 300°C.
Cerium(III) nitrate and urea solution mixture were treated by hydrothermal and microwavehydrothermal methods, as a result cerium(III) carbonate hydroxide nanoparticles (22-37 nm) were obtained. Cerium(III) carbonate hydroxide nanoparticles, encrusted by palladium were obtained using palladium reduction process from cerium(III) carbonate hydroxide solution. It is shown, that palladium occurrence disturbs hard hydrogen bond system, leading to carbonate hydroxide nanoparticles structure disorder and also increases efficiency of catalytic reactivity process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
