Evaluation of selected chemical processes for production of low-cost silicon (Phase III): silicon material task low-cost solar array project. Fourteenth quarterly progress report, January 1-March 31, 1979

Description: During this report period, a decision was made to defer the construction of the 50 MT Si/year Experimental Process System Development Unit (EPSDU) until FY 1980, and in the meantime to construct and evaluate, at full scale, four critical units of the EPSDU. The fluidized bed, zinc vaporizer, by-product condenser, and electrolytic cell have been combined with auxiliary units, capable of supporting 8-hour batchwise operation, to form the Process Development Unit (PDU), which is scheduled to be in… more

In-place calibration of moisture monitors

Description: An inexpensive, relatively quick calibration technique, used to calibrate moisture measuring instruments in Rocky Flats process lines is described. The moisture monitors utilize electrolytic cells to continuously monitor the moisture content of argon supply gases. The new method decreases the required down time of the measuring instrument from days to hours.

RESEARCH AND DEVELOPMENT IN THE FIELD OF THORIUM CHEMISTRY AND METALLURGY. VOLUME I. PREPARATION OF ELECTROLYTIC CELL FEED FOR PRODUCTION OF THORIUM METAL. Final Report

Description: A research and development program in the field of thorium chemistry and metallurgy was conducted. Most of this activity was directed toward the development of techniques for the production of metal by fused salt electrolytic approaches, little effort being proportioned to the preparation of an electrolyte for the process. An aqueous method for the preparation of an anhydrous cell feed was set up and operated for several months. Relatively high operating expense and difficulties with materials … more

RESEARCH AND DEVELOPMENT IN THE FIELD OF THORIUM CHEMISTRY AND METALLURGY. VOLUME III. COST ESTIMATE FOR 1,000 TON YR. THORIUM METAL PRODUCTION PLANT. Final Report

Description: The described plant will produce reactor grade Th at a price of 07 per pound. The plant operation is based on the preparation of electrolytic cell feed by fused salt chlorination techniques and converting the feed to high quality metal by high temperature electrolysis. (D.E.B.)

Electrodeposition of Plutonium

Description: Equipment for electrolytic deposition of plutonium from molten salt solutions was designed and built and was tested with cerium as a stand-in for plutonium. The electrolysis cell is a graphite crucible that serves as the anode; the cathode is a molybdenum rod. This paper discusses results of that test.

Final Report on Materials Characterization for the Wetted Cathodes for Low-Temperature Aluminum Smelting Program

Description: This report is a summary of materials characterization results on twenty cathode samples that were used in a novel aluminum reduction cell at the Northwest Aluminum Technologies laboratory. Most of these cathodes were based on the TiB2 composition and showed very little corrosion as a result of testing. Most of the samples also showed good wetting by Al metal that formed during cell operation.
