Biaxial Creep Behavior of Ribbed GCFR Cladding at 650 degrees C in Nominally Pure Helium (99. 99%)

Description: Biaxial creep-rupture tests were conducted on 12 prototypic GCFR fuel-cladding specimens at 650 deg C and a nominal hoop stress of 241.3 MPa. All test specimens were fabricated from 20% cold-worked Type 316 stainless steel tubes that were ribbed on the outer surface by mechanical grinding or electro-chemical etching. Test variables included specimen length and the presence or absence of weld-reinforcing end collars.

Advanced Fuel Cell Development Progress Report: April-June 1984

Description: Quarterly report discussing fuel cell research and development work at Argonne National Laboratory (ANL). These efforts have been directed toward seeking alternative cathode materials to NiO for molten carbonate fuel cells. Particular emphasis has been placed on studying the relationship between synthesis conditions and the resistivity of doped and undoped LiFeO2 and Li2 MnO3 and on achieving a better understanding of the crystalline defect structures of the thermodynamically stable phases.

Characterization of hot isostatically pressed Bi-Sr-Ca-Cu-O as a function of consolidation variables

Description: Fully dense, bulk Bi{sub 2}Sr{sub 1.7}CaCu{sub 2}O{sub x} (2212) superconductor pellets were made by hot isostatic pressing in an inert atmosphere. Electron microscopy revealed that rotation and bending of the platelike 2212 grains were responsible for much of the densification. Under processing conditions of 825{degrees}C and 105 MPa, dense pellets were obtained in 15 min. Many dislocations, planar faults, and, perhaps, intergrowths of the Bi{sub 2}Sr{sub 2}CuO{sub x} phase were produced durin… more

Synthesis of rare-earth-based oxides for the ceramic industry: From laboratory to pilot plant

Description: A wide variety of compounds, e.g., superconductors, chromites, and manganites, have been synthesized by spray drying a mixture of salts or a combination of salts and sols in a flash dryer. The process allows for good control of stoichiometry, morphology, particle size, and surface area. Appropriate particle-growth and synthesis heat treatments of these fine powders were performed. The resultant powders were evaluated for possible applications in fuel cells and superconductors. The processes hav… more
