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...

Creator:: Kouts, Daberath
Abstract:: Direct current conductivity measurements on KC1:O[superscript]= crystals were used to determine an enthalpy of 0.42 ev for the dissociation for anion-vacancy-oxide ion complex. The entropy of dissociation was found to be approximately -4x 10⁻⁴ev deg⁻¹. The intrinsic "activation" energy was found to be 1.91 ev as compared to 1.95 ev,...

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...

Creator:: Seevers, Robert Edward
Abstract:: When the dc conductivities of various pure KC1 crystals were compared it was found that crystals grown under an HC1 atmosphere, from salt purified by ion exchange, exhibited lower knee temperatures than any of the crystals studied. These knee temperatures were found to be approximately 350°C. From this the total...
