Synthesis and Rietveld analysis of Zn4−xCdxSb3 bulk crystals in the Zn-rich region

Tetragonality and Properties of Ba(Zr x Ti1−x )O3 Ceramics Determined Using the Rietveld Method

“…Moreover, the density of the BZT solid solution decreases as the Zr content increases, as seen in Table II. Souma and Ohtaki [15] have demonstrated that the density of the bulk crystal estimated by the Rietveld method is very close to the measured value. The higher the density, the lower the vacancy or void in the ceramics, resulting in both a higher dielectric constant and a lower Curie temperature.…”

Cd Substitution in MxZn4−-xSb3: Effect on Thermal Stability, Crystal Structure, Phase Transitions, and Thermoelectric Performance

“…Many investigations have been carried out on the properties of Cd 4 Sb 3 , which has an analogous structure to Zn 4 Sb 3 . , There has been some discussion about the solid-solution range of Cd 4 Sb 3 −Zn 4 Sb 3 . Record et al found the solubility of Cd in Zn 4 Sb 3 to be ∼43 at %, giving a maximum formal stoichiometry of Zn 2.28 Cd 1.72 Sb 3 , whereas Nakamoto et al reported a maximum Cd stoichiometry of Zn 2.4 Cd 1.6 Sb 3 . , A solubility of 50 at % has also been reported by Ohtaki et al using the vacuum casting method without annealing . However, a study by Kuznetsov et al showed a maximum Cd stoichiometry of only Zn 3.76 Cd 0.24 Sb 3 .…”

Discontinuous precipitates in age-hardening CuNiSi alloys

“…These suggest that the calculated pattern for the δ-Ni 2 Si is in good agreement with the measured results. This is supported by the fact that the indicator of the accuracy of the Rietveld fitting, S, was 1.64, thus indicating that the Rietveld analysis had a high level of reliability [26]. We can therefore conclude that the DPs were identified as being δ-Ni 2 Si, i.e., both the CPs and DPs have the same crystal structure.…”
