A thermodynamic study of the sulphates and related compounds of alkali and alkaline earth metals at high temperatures

Powell, David Guy January 1971 (has links)
The vapour pressures of various salts have been investigated at high temperatures and the results are presented here together with the values found by previous investigators. Sodium sulphate is extensively used in the glass producing industry and it is in this compound that interest is centred. Other salts have been included in this study for the purpose of comparison. The use made of sodium sulphate in glass making is discussed briefly below. Work previously reported on the determination of the vapour pressure of sodium sulphate will be shown to have produced confusing results, and it was for the purpose of introducing some harmony into the sometimes discordant evidence that the present work was undertaken.

An ion exchange separation of the rare earths from naturally occurring materials with a view to the isolation of element number 61.

Perkins, Harold Jackson January 1953 (has links)
The extraction of the Rare Earths from two kilograms of Lindsay Light and Chemical Company's "monazite residues" (hydrated Rare Earth oxides), from two kilograms of Norwegian gadolinite, and from five kilograms of Lindsay's "didymium carbonate" (Code 411) gave a mixture of Rare Earths which, after purification, fractional crystallisation as the double magnesium nitrates and ion exchange separation, showed some evidence for the existence of naturally occurring element number 610. This evidence took the form of unexplained lines in the arc spectra, anomalous absorption bands, aid an unexplained peak in the elution curve obtained from the ion exchange work. The evidence presented is far from conclusive and the suggestion is made that further research along these lines be carried out. / Science, Faculty of / Chemistry, Department of / Graduate
