New pathway for the preparation of pyrochlore Nd2Zr2O7 nanoparticles

Crystal chemistry and ion‐irradiation resistance of Ln2ZrO5 compounds with Ln = Sm, Eu, Gd, and Tb

“…These two samples appear distinctly different; there is much greater porosity in the mixed oxide route fabricated sample, and there is also poorer homogeneity indicated via variation in the intensity of grey‐scale in this sample relative to the wet‐chemistry approach. Previous studies have shown that improved mixing at the molecular level is achieved via this wet‐chemistry approach leading to improved homogeneity 19,50 . The software ImageJ 51 was utilized to investigate the porosity of the SEM backscattered images for Figure 1, where the measured porosities were 15.6% and 27% for the wet‐chemistry and mixed oxide route respectively (Figures S2‐S3 at SM).…”

While there may be some variation in calculated values for porosity depending on the image contrast thresholding used, this source of error should be consistent if the same approach is used for each image.…”

Surface thermodynamics of yttrium titanate pyrochlore nanomaterials

“…83 Among these, sol-gel methods adapting the Pechini approach based on polymeric precursors has resulted in a large body of published work with pyrochlore nanomaterials of small size and high phase purity. 45,[84][85][86][87][88][89] Nanocrystalline Y 2 Ti 2 O 7 pyrochlore powders were synthesized according to previously published methods using a modified citric acid sol-gel route described by Chen and Wen (Fig. S1 †).…”

Microstructure, electrical and humidity sensing properties of light rare earths zirconates

“…There are a variety of methods for preparing zirconate material a through solid state reaction [18], complex-precipitation in aqueous media [19], sol-gel [20], easy-calcination sedimentation [7] etc. In our investigations, Ln 2 Zr 2 O 7 zirconates of light rare earths elements (Ln = La, Nd, Sm, Eu, and Gd) were produced by liquid route.…”
