Electrical and optical properties of potassium chloride single crystals containing lead ion

Creator:: Holmes, Robert Edward
Abstract:: A survey of the methods of purification of KC1, for use in preparing single crystals by growth from the melt, was made. Two methods, fractional recrystallization and ion exchange, were used. The purity of the salt and crystals grown from the same salt were compared with the findings of other...

An investigation of the absorption spectra of EGTA metal complexes and the development of spectrophotometric methods for the analyses of copper, erbium, europium, holmium, neodymium, and praseodymium

Creator:: Holmes, Ivan Gregory
Abstract:: The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)] tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions. The absorption spectra of the chelates formed were measured with a recording spectrophotometer between 200 and 700 mμ. The pH of each solution was varied and a spectrum was scanned...

The conductivity of lead oxide doped potassium chloride single crystals

Creator:: Knepp, Donald Jack
Abstract:: A comparison was made of the d.c. conductivity of KCI:Pb²⁺ and KCl:PbO single crystals at temperatures greater than 325°C. The energy of activation was 0.72 ev for all crystals. Lead concentration was determined by chemical, optical and electrical methods. The half band width of the UV absorption band at 273...

Preparation and Lewis acid properties of diboron tetrafluoride and related compounds

Creator:: Hansen, John Donald
Abstract:: Attempts to synthesize diboron tetrafluoride by the reduction of boron trifluoride with alkali metal solutions in 1, 2-dimethoxyethane proved to be unsuccessful. No diboron tetrahalide was found when boron trifluoride, antimony trifluoride, or boron trichloride was reacted with tetra-(dimethylamino)-diboron; although there appeared to be some exchange between chloride and amine...

I. Infrared spectra of solid solutions in alkali halide crystals [and] Method for obtaining minimal kinematically complete sets of internal coordinates

Creator:: Conant, Donald Robertson
Abstract:: A study was made of the infrared absorption spectrum for cyanate ion in KCl and KBr host lattices containing small amounts of calcium or barium ion. Both pellets and single crystals were scanned during the course of this study. The spectra of the barium or calcium doped crystals contained many...

The effect of impurities on the gamma-ray coloration of potassium chloride crystals

Creator:: Hinks, David George
Abstract:: The incorporation of europium and dysprosium in potassium chloride crystals was investigated. The crystals were prepared by the Kyropoulos method from melts containing the rare-earth chlorides. The concentration of these rare-earth ions in the crystals was determined by neutron-activation analysis. The distribution coefficient of europium and dysprosium between the molten...

Low temperature thermal analysis of some boron halide complexes with weak Lewis bases

Creator:: Lerch, Ronald Edwin
Abstract:: Thermal analysis was used to investigate the following seven systems: H₂S-B₂F₄, SOF₂-B₂F₄, COC1₂-B₂F₄, SF₄-B₂F₄, Xe-BF₃, NF₃-BF₃, and NF₃-BC1₃. In two of the seven systems compound formation was observed. In the system, H₂S-B₂F₄ the compounds H₂S[superscript .]B₂F₄ and 2H₂S[superscript .]B₂F₄ are formed. The compound H₂S[superscript .]B₂F₄ has a melting point of...
