Synthesis of monodispersed La2Ce2O7 nanocrystals via hydrothermal method: A study of crystal growth and sintering behavior

The Control of Sensing Properties for Sm2O3-ZrO2 Humidity Sensor

“…While for pure ZrO 2 , the whole mass loss is 1.43%. The mass losses for both samples mainly came from the decomposition of organic substances and the evaporation of physically absorbed water [8]. In the case of DSC curves, both samples have an exothermic peak at about 90 o C, which can be due to the elimination of residual organic substances [9].…”

“…Detailed steps can be reference [8]. For comparison, the pure ZrO 2 nanopowders were synthesized by the same procedure.…”

“…The crystalline phases of nanocrystalline powders were identified by powder X-ray diffraction (XRD, Bruker D8 Focus powder X-ray diffractometer) using Cu Kα radiation (λ=1.5406 Å) with a scanning rate of 5°min -1 . The operation voltage and current were maintained at 40 kV and 40 mA, respectively [8]. The mean particle size of powders (D) was determined by Scherrer's equation.…”

“…Su et al studied the Y 3+ and Mg 2+ doped zirconia thick film humidity sensors [7]. Wang et al reported the properties of nano-structured films humidity sensor with commercial ZrO 2 nanoparicles [8]. To the best of our knowledge, however, the performance of humidity sensors controlled by doping Sm 3+ for ZrO 2 sensor has not been reported.…”

Ce1−x Sm x O2−x/2—A novel type of ceramic material for thermal barrier coatings

“…Except for the A 2 B 2 O 7 -type (A = rare earth element, B = Zr, Ce, Hf, Sn) oxides [1][2][3][4][5][6][7][8][9][10], the cerium oxides with fluorite structure have recently attracted extensive attention due to a diversity of applications, such as conversion catalysts for selective hydrogenation of unsatured compounds, catalysts for three-way automobile exhaust systems, abrasives for chemical polishing slurries, gates for metal-oxide semiconductor devices, and luminescent materials for violet/blue fluorescence [12][13][14]. Now, the rare earth doped CeO 2 (RE 2 O 3 -CeO 2 ) have also been considered to be new materials for TBCs and solid oxide fuel cells due to the excellent electrical, mechanical, and thermophysical properties [15][16][17]. For example, Cao et al [18] [21].…”
