Density measurements of molten solutions of thallium
and tellurium have been made over the temperature range
220 to 650°C and the composition range 31 to 69 atomic
per cent thallium. The Archimedian method was employed
since it is readily adaptable to performing measurements
over wide ranges of temperature and composition...
The oxidation of triethylamine by the two electron oxidant
thallium(III) chloride was studied and the results compared to those
when triethylamine is oxidized by copper(II) halides. This study
requires anhydrous conditions since in an aqueous system thallium(III)
chloride is extensively hydrolyzed and triethylamine causes
precipitation of thallium(III) oxide. Most of...
Measurements are made of the conductivity and Hall mobility of
liquid solutions of thallium-tellurium, in compositions ranging from
pure tellurium to 69.0 atomic percent thallium. At compositions on
the thallium-rich side of intrinsic composition (66.7 atomic percent
thallium) both the conductivity and Hall mobility are temperature
independent, and the data...
Electrical resistivity and thermoelectric power measurements
have been made over the temperature range of 450° to 600°C on
n-type liquid thalliurn-tellurium solutions. Liquids with compositions
from 61.5 to 72.0 atomic percent thallium were studied. In addition,
alloys of some of the three component thallium-teIlurium solutions
containing small amounts of silver,...
