Author is Moschner, Goril; Lothenbach, Barbara; Winnefeld, Frank; Ulrich, Andrea; Figi, Renato; Kretzschmar, Ruben.

The solid solution between Al- and Fe-ettringite Ca6[Al1-xFex(OH)6]2(SO4)3·26H2O was investigated. Ettringite phases were synthesized at different Al/(Al + Fe)-ratios (= XAl,total), so that XAl increased from 0.0 to 1.0 in 0.1 unit steps. After 8 mo of equilibration, the solid phases were analyzed by X-ray diffraction (XRD) and thermogravimetric anal. (TGA), while the aqueous solutions were analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). XRD analyses of the solid phases indicated the existence of a miscibility gap between XAl,total = 0.3-0.6. Some of the XRD reflections showed two overlapping peaks at these molar ratios. The composition of the aqueous solutions, however, would have been in agreement with both, the existence of a miscibility gap or a continuous solid solution between Al- and Fe-ettringite, based on thermodn. modeling, simulating the exptl. conditions.

This study aims to verify the influence of the apparent mol. size of aquatic humic substances (AHSs) on the effectiveness of coagulation with Al sulfate and ferric chloride. Coagulation-filtration tests using the jar test and bench-scale sand filters were carried out with H2O samples having a true color of ∼100 Hazen units and prepared with AHSs of different mol. sizes. Stability diagrams are presented showing regions of ≥ 90% and ≥ 95% apparent color removal delineated for each H2O sample using plots of total metal ion concentration (Al3+ and Fe3+) vs. coagulation pH. To achieve the same degree of color removal, the H2O samples with smaller apparent mol. sizes and a higher percentage of fulvic acids required higher dosages of both Al sulfate and ferric chloride.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Alumina-coated hollow glass spheres/alumina composites, published in 1997-11-15, which mentions a compound: 17927-65-0, mainly applied to alumina coating glass hollow sphere, Electric Literature of Al2H8O13S3.

Coating of alumina onto the surface of hollow glass spheres was accomplished by controlled heterogeneous precipitation from aqueous solutions The processing conditions were optimized to yield thin and uniform precursor coatings. After calcination, converting the precursor to alumina, the alumina-coated hollow glass spheres formed free-flowing powders that were used to produce glass sphere/alumina matrix composites with up to 35 vol% of controlled and well-dispersed closed porosity. The dielec. constants and the flexural strengths of such porous composites were determined as a function of porosity.

No SO2 was detected by the mass spectrometer. The primary products of decomposition appear to be SO and O2 for both sulfates. For the Al salt, the Arrhenius relationship shows 2 activation energies, whereas for the Hf salt there is only 1 activation energy in vacuum and 2 activation energies in air. X-ray data show the solid products of the reactions to be η-Al2O3 and HfO2. The diffraction pattern for Hf(SO4)2.4H2O is presented.

A novel preparation of aluminum diethylphosphinate (AlPi) was carried out with free-radical addition reaction by means of UV-irradiation under atm. pressure. A solution of sodium hypophosphite was treated with ethylene and irradiated with UV light in the presence of an amount of photoinitiator effective to initiate the free-radical reaction between the hypophosphite anion and the double bond of the ethylene mol. The ethylene was micro-bubbled into the reaction mixture with the addition of the photoinitiator, and the gas-liquid contact surface and the photoinitiator concentration in the gas-liquid interface were increased largely. The yield of the final product could be improved to about 96%. The contents of P, Al in samples were detected by ICP, and the mol. structure of the samples was confirmed by 31P NMR, 1H NMR and FTIR spectroscopic anal.
