This page contains several tables detailing the standard thermodynamic properties for several different substances. The table has been separated by substance, as listed below: Beryllium. Standard Thermodynamic Properties for Selected Substances; Substance K(g) KF(s) – – KCl(s) – –   Calculations and comparisons of average values of the standard Gibbs free energy for the formation of beryllium silicates are used to expand a known series that orders them by decreasing activity. The series is expanded to also include huegiant, barillite, spherobertrandite, eudidymite, beryllite, and chkalovite: chkalovite > beryllite > eudidymite > danalite > spherobertrandite > genthelvine.

Enthalpies. Enthalpy of fusion: kJ mol-1; Enthalpy of vaporisation: kJ mol-1; Enthalpy of atomisation: kJ mol-1; Thermodynamic data. This table gives a few thermodynamic data for values are those given in the NBS technical notes (reference 1) after conversion from the units used within those notes.

containing dissolved beryllium sulfate is separated from the solids by countercurrent decantation thickener resulting solution contains – g/1 Be, 4–7 g/1 Al, 3–5 g/l Mg, and g/l Fe, plus assorted other minor impurities. Salts, basic, such as BERYLLIUM SULFATE TETRAHYDRATE are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than They react as bases to neutralize acids.

Thermodynamic properties of beryllium sulfate from 0 to k Technical Report Taylor, A.R. ; Gardner, T.E. ; Smith, D.F. Heat capacity and enthalpy values were determined for beryllium sulfate (BeSO/sub 4/) from 10 to un. The thermodynamic properties of beryllium have been evaluated up to K.

A further evaluation is justified by the inclusion of not only new specific heat measurements at low temperature but also new enthalpy measurements at high temperature which lead to a reassessment of the enthalpies and entropies of transition and fusion.

Selected values include an enthalpy of Cited by: 7. Beryllium sulfate normally encountered as the tetrahydrate, [Be(H 2 O) 4]SO 4 is a white crystalline solid. It was first isolated in by Jons Jakob Berzelius. Beryllium sulfate may be prepared by treating an aqueous solution of any beryllium salt with sulfuric acid, followed by evaporation of the solution and hydrated product may be converted to anhydrous salt by Chemical formula: BeSO₄.

Occurrence, properties, and uses. Beryllium is a steel-gray metal that is quite brittle at room temperature, and its chemical properties somewhat resemble those of does not occur free in nature.

Beryllium is found in beryl and emerald, minerals that were known to the ancient gh it had long been suspected that the two minerals were similar, chemical. Beryllium is a chemical element with the symbol Be and atomic number 4.

It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic the cores of stars, beryllium is depleted as it is fused into heavier elements. It is a divalent element which occurs naturally only in combination with other.

Pure beryllium is a hard gray metal that does not occur naturally but does occur as a chemical component of certain kinds of rocks, coal and oil, soil, and volcanic dust.

Beryllium itself is an expensive material, yet it is not often a major contributor for the final cost of the mirror. The grade chosen and beryllium content can affect the raw material cost by up to 50%.

Aluminum-Beryllium is a lower cost alternative but the mixture negatively impacts many of the desired properties of pure beryllium. Most widespread minerals containing Beryllium; This list of minerals containing Beryllium is built from the locality database.

This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Beryllium mineral.Thermodynamic Properties of Mixtures.
