TL;DR: It is justifiable to recommend that the maximum zinc content to be permitted in zinc-free type alloys should not be greater than 0.01%, and this value was subsequently incorporated in the revised Australian standard 2110-1977: Alloy for Dental Amalgam.
Abstract: Analyses of 51 alloys (conventional, 41, and high-copper, 10) currently available in Australia were made. A rapid and precise procedure was developed that relied on wet-way methods for silver and tin while copper, zinc, mercury, indium and low-level constituents, such as lead, cadmium and antimony, were determined by atomic absorption spectroscopy. The conventional alloys, with two minor exceptions, all complied with the compositional requirements of modern standards and little quantitative variations was noted when the range of the major component was compared with the values obtained in two surveys made over thirty years ago. The high-copper contained, among other factors, an average copper concentration about four times that of conventional alloys. Rather surprising were the contents of mercury, indium, and cadmium found in some of the alloys as well as the low-level concentration of lead, and in a few cases antimony. Other elements were not detected by the sensitive technique used. It is justifiable to recommend that the maximum zinc content to be permitted in zinc-free type alloys should not be greater than 0.01%, and this value was subsequently incorporated in the revised Australian standard 2110-1977: Alloy for Dental Amalgam.

TL;DR: In this paper, it was shown that while the crystallinity of the films increases with increasing temperature, the phase purity decreases due to antimony volatility, and the diantimonide phase is nucleated if the distance is too large.
Abstract: Skutterudite (CoSb3 and IrSb3) thin films of high phase purity and crystallinity have been prepared by pulsed laser deposition. It is found that while the crystallinity of the films increases with increasing temperature, the phase purity decreases due to antimony volatility. The skutterudite phase can be stabilized to higher temperature by addition of excess antimony to the pulsed laser deposition target. Target-to-substrate distance must be optimized to obtain stoichiometric skutterudite films with low stress. A decrease in the flux of energetic particles and changes in particle stoichiometry with increasing distance caused by plume tilting results in lower film stress, but the diantimonide phase is nucleated if the distance is too large. It is possible to further reduce compressive stress by growing films in an inert background gas to decrease the flux of energetic particles. Overall, the highest quality films are grown from targets with excess antimony at a temperature of 270 °C with a target-to-substrate distance of 7 cm and a background argon gas pressure of 10 mTorr. The resistivity, mobility, and carrier concentration of these films are indicative of a degenerate p-type semiconductor with hole concentrations in the range of previously measured bulk values.

TL;DR: In this article, the isomer shifts relative to the 121SnO2 source are − 11.3 mm/sec (Sb2O3), − ǫ 13.8 (Sbr3), + ǔ 2.2 (SabbF5), and − 3.12 (sbCl5).
Abstract: Mossbauer spectra of 121Sb in all the binary antimony halides have been obtained, as well as in cubic Sb2O3. The isomer shifts relative to the 121SnO2 source are − 11.3 mm/sec (Sb2O3), − 13.8 (SbCl3), − 13.9 (SbBr3), − 15.9 (SbI3), − 14.6 (SbF3), + 2.2 (SbF5), and − 3.12 (SbCl5). Quadrupole splittings were obtained for most of the antimony(III) compounds. The linear variation of isomer shift with ligand–metal electronegativity difference for Sb2O3, SbCl3, SbBr3 and SbI3 is interpreted as due to a constant s character in the ligand–metal bonds. The SbF3 does not obey this relationship due to its radically different geometry.

TL;DR: In this paper, the nonlinear refractive index of antimony polyphosphate glasses measured using the Kerr shutter technique was reported to be (1.1±0.2)×10−14 cm2/W at 800 nm.
Abstract: We report on the ultrafast nonlinearity of antimony polyphosphate glasses measured using the Kerr shutter technique. The nonlinear refractive index, n2, was (1.1±0.2)×10−14 cm2/W at 800 nm, and enhancement of n2 by ≈80% was observed by adding 10% of lead oxide in the glass composition. The full width at half-maximum of the third-order correlation signal was 150 fs, which implies a fast response of the samples (⩽100 fs). Nonlinear absorption was negligible in the range of intensities used.

TL;DR: Mesoporous Co3O4@rGO nanocomposite is a potential candidate for antimony removal from waste water and its adsorption performance toward highly toxic antimony ions indicates that it is an excellent adsorbent forAntimony removal.
