摘要:
A method for purifying crude argon is disclosed. Trace amounts of oxygen and/or nitrogen are removable by using a combination of a nitride forming metal and an oxygen ion conducting electrolyte cell. Lithium may be electrolytically recovered from lithium nitride. Alternatively, a reactive metal such as lithium may be utilized to remove trace amounts of both nitrogen and oxygen from crude argon.
摘要:
Mixed oxygen ion and electronic conducting bismuth oxide based ceramic materials having high ambipolar activity which can be fabricated into thin membranes for high efficiency oxygen separation from air at intermediate temperatures. The ceramic materials may be homogeneous microstructures in the form of solid solutions or compounds or may be composite non-homogeneous microstructures of a separate substantially continuous oxygen ion conductive phase and a substantially continuous electronic conductive phase.
摘要:
An electrolyte for solid-state electrochemical cell comprising in solid state, a combination of lithium, phosphate and iodide and either calcium or aluminum moieties, the non-metallic moieties being in stoichiometric relationship with the metallic moieties. An advantageous electrolyte is prepared by reacting calcium iodide and lithium orthophosphate.
摘要:
A solid state electrochemical cell containing a cathode comprising a compound which is solid at ambient temperatures and which contains a halogen atom, a chalcogen atom and an atom of a third element, with the chalcogen and halogen not in a redical grouping.
