The Kroll Process for the production of zirconium utilizes
the reduction of zirconium tetrachloride with metallic magnesium.
Control of the magnesium content of the final zirconium metal is
essential, as residual magnesium adversely influences the properties
of zirconium.
In this thesis a volumetric method has been presented for the
determination...
New alloys containing refractory metals have been developed
by the aero-space industry to meet the demand for thermally resistant
materials. The chemical analysis of these alloys has been
handled successfully by the use of ion exchange. Hydrofluoric acid,
either alone or combined with hydrochloric acid, has here-to-fore
been used to...
Many different aspects of the determination of dissolved oxygen
by controlled potential coulometry were investigated to find a means
of measuring the oxygen content of natural waters. Rapid
sampling techniques, simplicity of operation, and rugged structural
features were stressed. Cells were designed to operate by either
internal electrolysis or external...
An all-glass gas chromatograph was developed for the analysis
of corrosive metal halides. Included in the apparatus is a new liquid
sampling system designed for fast repetitive sampling of corrosive
liquids in an inert atmosphere. A flame photometer detector was developed
to permit the detection of corrosive solutes in the...
