Coprecipitation synthesis and thermal conductivity of La2Zr2O7

Synthesis, Characterization and Thermal Diffusivity of Holmium and Praseodymium Zirconates

“…[13,20] the influence of grain boundaries is considered negligible. However, it was also reported [21] that pyrochlore-fluorite boundaries might decrease thermal conductivity, as well as grain boundaries in different materials [22][23][24], including pyrochlore and fluoriterelated [25]. More detailed studies are planned in future to explain the differences in thermal properties of dual phase RE zirconates.…”

“…co-precipitation [6], sol-gel [7] and hydrothermal method [8]. The commonly emphasized advantage of sol-gel type of methods is homogeneity of synthesized compound and precise control over its stoichiometry.…”

An electron spin resonance and photoluminescence investigation of the effect of annealing temperature on Gd-doped La2Zr2O7 nano-ceramics

“…However, the most commonly used metal alkoxides (as starting materials for the synthesis) are often hygroscopic and extremely sensitive to moisture, necessitating the use of a stabilizer or nonaqueous solvents [25,19]. Moreover, in case of samples prepared via co-precipitation route, the final is often a mixture of different metal hydroxides due to the variation of precipitation rates of different cations [26]. Kong et al have reported a novel sol-gel route for the preparation of LZO pyrochlores with better homogeneity and uniform density [27].…”

Dissolution of ZrO2 based pyrochlores in the acid pH range: A macroscopic and electron microscopy study

“…The synthesis of the powder was carried out according to Chen (Chen et al, 2009) and similar to the samples presented in Finkeldei et al (2013). 0.1 mol L À1 aqueous solutions of ZrOCl 2 Á8H 2 O and Nd(NO 3 ) 3 Á6H 2 O (99.9% purity, Alfa Aesar) were prepared.…”
