TL;DR: In this article, a chemically untreated clay is mixed with aluminium hydroxide, and, if desired with poreforming substances and lubricants, the resulting mixture is formed into shapes which are dried at a temperature of about 100 DEG C. or below, and then kilned at about 900-1200 DEGC.
Abstract: A chemically untreated clay is mixed with aluminium hydroxide, and, if desired with poreforming substances and lubricants and the resulting mass is shaped, dried at 100 DEG C. or less and kilned at about 900-1200 DEG C. Clays mentioned are halloysite, montmorillonite, sepiolite, attapulgite and kaolinite. Examples are given.ALSO:In a method of producing high temperature-resistant shaped carriers of high mechanical strength for catalysts, a chemically untreated clay is mixed with aluminium hydroxide, with the possible addition of pore-forming substances and lubricants, the resulting mixture is formed into shapes which are dried at a temperature of about 100 DEG C. or below, and then kilned at about 900-1200 DEG C., preferably 1000 -1100 DEG C. Specified clays are Kaolinite, halloysite, montmorillonite, sepiolite, fireclay and attapulgite. Possible additives mentioned are stearic acid, polyvinyl alcohol, or an emulsion of a synthetic wax. Specified metals or compounds thereof which may be supported on such carriers are Group VIII metals, Cu, Ag, Mn, Cr, Mo, W, V, Ti, Th and Ce. Miscellaneous catalyst constituents include dextrin and active carbon.

TL;DR: In this article, electron spin resonance (ESR) and electronic spectra of gels of amorphous aluminium hydroxide after adsorption of copper(II), in the presence of O-phospho-L-serine or O -phosphoencoder-l-tyrosine, from aqeous solutions over the pH range 4-8, indicated the formation of complexes having 1:1 or 1:2 metal-to-ligand ratios.

TL;DR: In this article, the pH in CaCl2 suspensions of some acid Scottish soils increase with time, in some cases by 0·4 units in 24 hours, attributed to proton uptake by a complex ion displaced into solution, and to obtain unambiguous values, pH should be measured within an hour of making up the suspensions.
Abstract: Summary
pH values in CaCl2 suspensions of some acid Scottish soils increase with time, in some cases by 0·4 units in 24 h. This is attributed to proton uptake by a complex ion displaced into solution, and to obtain unambiguous values, pH in CaCl2 suspensions should be measured within an hour of making up the suspensions.
In moderately to strongly acid soils, lime potential (LP) and aluminium hydroxide potential (AHP) vary with salt concentration and soil: solution ratio. Unique values for these ion-activity ratios can be obtained by equilibration with a single solution only when the reference cations, i.e. (Ca2++Mg2+) for LP, and Al3+ for AHP, are the dominant exchangeable cations. Otherwise, equilibrium values should be obtained by interpolation from an exchange isotherm at the point where no exchange occurs, i.e. where Δ(Ca+Mg) = o for LP values and ΔA1 = o for AHP values.

TL;DR: In this article, the densification and phase transformation of mullite and alumina composites prepared from cordierite and aluminium hydroxide mixture were investigated. And the presence of spinel and mullite phases can be detected by X-ray diffraction and confirmed by Xray photoelectron spectroscopy.
