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...

Single CrystalsContaining Lead Ion AN ABSTRACT OF THE THESIS OF ROBERT EDWARD HOLMES for the Ph. D
Electrical conductivity of additively colored potassium chloride crystals

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...
