“…Using 129 kJ · mol -1 , the corresponding boiling point is 1460 K, which is closer to 1466 K (within 0.40 %), and this value is confirmed by the work of Habermann and Daane. 28 In their work, the vapor pressures of the rare-earth metals were measured by the Knudsen effusion technique using a quartz-fiber microbalance, and then a combination of second and third law methods were used to calculate the normal boiling point for each rare-earth metal, and for Yb this value is 1466 (( 5) K.…”

The scientific community relies upon the veracity of the scientific data in handbooks and databases. In a previous work, the authors developed a systematic, intelligent, and potentially automatic method to detect errors in such resources based on artificial neural networks (ANNs). This method revealed variations from (10 to 900) % in tables of property data for elements in the periodic table and pointed out the ones that are most probably correct. In this paper, we focus on the details of employing this method for analyzing the data of boiling points and enthalpies of vaporization recorded in different handbooks. The method points out the values that are likely to be correct. To verify the method employed, a detailed discussion of the data with reference to the original literature sources is given as well as factors that may affect the accuracy of the prediction.

“…Investigation of the Gd 2 O 3 vaporization has been carried out in a number of studies . In the temperature range 2114–2330 K the dependence of the GdO partial pressure over pure Gd 2 O 3 on temperature was also obtained by Knudsen mass spectrometry in our laboratory:

log p ((),, GdO, Pa) = - \frac{(31285 \pm 1556)}{T} + ((),, 12.90 \pm 0.71) .

“…The Sm sample was not, however, doped with Ag. The benefit of Sm arises from its high vapor pressure at lower temperatures (Habermann & Daane, 1964), which allows the operation of an Sm sublimation source, thus, reducing the cost of processing. The layer stack was finally terminated with an Ag coating, acting as a protective layer to dissipate heat and current in the event of electronic quenching.…”

In the field of high-temperature superconductors, atom probe tomography is a relatively new instrument, with the ability to provide a new perspective on the 3D nanoscale microstructure. However, field evaporation of nonmetallic materials is fraught with unique challenges that matter little in the world of metallic evaporation. In this study, we review the laser absorption, correlated evaporation, molecular dissociation, and the crystallographic effects on the field evaporation of 800-m ${\rm RB}{\rm a}_ 2{\rm C}{\rm u}_ 3{\rm O}_{ 7-{\rm \delta }}$ (R = Gd, Sm) coated conductor tapes deposited by Reactive Co-Evaporation Cyclic Deposition and Reaction (RCE-CDR). Ultraviolet 355 nm laser pulsing was found to have a substantial beneficial effect on minimizing the fracture probability compared with 532 nm illumination, especially when evaporating insulating oxide precipitates. This, in turn, allows for the 3D compositional analysis of defects such as flux pinning centers introduced by precipitation and doping. As a result, evidence for the precipitation of nanoscale ${\rm G}{\rm d}_ 2{\rm C}{\rm u}_ 2{\rm O}_ 5$ is discussed. The effect of crystallographic orientation is studied, where [001] aligned evaporation is found to develop compositional aberrations.
