Synthesis of Advanced Ceramic Compounds by Intercalation

Description: The U.S. Bureau of Mines investigated the synthesis of advanced ceramics (SiC+AlN, SiAlON, SiC+Al 203 , and Si 3N4 +AlN) from natural clays (kaolin, halloysite, or montmorillonite) by an intercalation and heat treatment method. This process includes the steps of refining a clay, intercalating organic chemicals into its layered structure, drying the intercalated mixture, firing the treated structure at certain temperature ranges in controlled atmospheres to form desired compounds, and grinding the loosely agglomerated structure. Focus of this research is to economically process advanced ceramic structures from abundant natural resources. The advanced ceramic phases produced in this simple treatment are homogeneously distributed at the nanostructure level, and may potentially lead to cost effective manufacturing processes. The intercalation of clay was confirmed by X-ray and BET analyses. The evolution of chemical compositions during carbonization reactions and carbothermal reduction was investigated. The characteristics of refined clays and synthesized powders were studied. Advanced ceramic composites/solid solution have been produced from intercalated clays, without the presence of other compounds.

Influence of Bath Composition at Acidic pH on Electrodeposition of Nickel-Layered Silicate Nanocomposites for Corrosion Protection

Description: This article describes how nickel-layered silicate nanocomposite films were electrochemically deposited using pulsed potentiostatic conditions from an acidic plating bath containing exfoliated layered silicate to enhance adhesion to the substrate, corrosion resistance, and mechanical properties.

Welding Thin-Walled Uranium Cylinders

Description: One of Its Monograph Series, The Industrial Atom.'' The development of a satisfactory process for the fusion welding of thin-walled uranium cylinders is discussed. Optimum results were obtained using the inert-gas shielded-arc method without the use of filler metal. The ductility of the welded joints, however, was lower than that of cast metal. Surface conditions and and the purity of the inert gas used affected the weld soundness. Straight polarity direct current was used for welding to achieve maximum penetration and to provide are stability. Welding must be done in the flat position. (auth)

FUNDAMENTALS OF SINTERING--II. Second Annual Progress Report, June 30, 1956 to June 30, 1957

Description: Rates of spheroidization and densification of gold and of nickel wire compacts were measured as a function of time, temperature, and wire size. The necks joining the sintered particles were found to grow proportionally to the one- fifth root of time. The value of the coefficient of self-difiusion calculated from the sintering rate is of the sane order of magnitude as that obtained by ordinary tracer techniques but with a somewhat higher activation energy. These results are entirely consistent with those predicted by the Kuczyrski diffusional theory of sintering, as is the effect of wire size on sintering rate. The experiments did not reveal a clear effect of grain boundaries on sintering rates. This may be due to a relatively slow densification of the nickel wire compacts at even 0.98 of the absolute melting point, which obscured the effect of grain growth on sintering rate. (auth)

MTR FUEL ELEMENTS CONTAINING PLATES WITH Pu-Al ALLOY

Description: The first group of Pu--Al MTR fuel elements fubricated were rejected for excessive dimensions and blistering. The fuel element constitution and fubrication was reviewed, and a new Pu--Al ratio and revised rolling techniques were suggested. (D.E.B.)

USE OF AGGLOMERATED UO$sub 2$ IN PRESSURE-BONDED STAINLESS STEEL-CLAD FUEL RODS

Description: In a continuation of the Hanford-Battelle cooperative program, the combined use of the vibrational-compaction and gas-pressure-bonding processes for fabricating UO/sub 2/ fuel elements was studied. Particuliar emphasis was placed on the use of agglomerated micronized UO/sub 2/ to overcome nonuniformities in the vibrationally compacted pressurebonded fuels. Inconel-X-clad fuel rods were gas-pressure bonded at 2100 deg F for 3 hr at 10,000 psi to evaluate the use of micronized UO/sub 2/ agglomerated by cold high-energy-rate forming methods. Fuel densities from 88 to 93% of theoretical were attained. A limited parallel study was also conducted a evaluate hydrostatic pressing as a method of agglomerating micronized UO/sub 2/. Tap density increased from 20 to 25% for the as-received micronized oxide to 41% for the hydrostatically agglomerated plus 200-mesh powder. Studies of the effects of prior cold work and gaspressure bonding on the mechanical and physical properties of types 304L and 347 stainless steel were conducted. Prior cold work in the range of 35 to 50% gave a pressurebonded structure having a fine grain size. (auth)

Atomization Method of Making Uranium Powder

Description: Atomized U powder was produced by forming an electric arc between two U electrodes in an inert atmosphere and sending a high velocity stream of inert gas through the arc. Uranium particles obtained by this method were of spherical shape; smaller particles contained mostly small grains, and larger particles wore characterizcd by larger grains. The particles were ductile and could be hotpressed to a compact of high density. The temporary equipment used for those preliminary tests on atomization was not adequate to control particle size. Suggestions for the production of atomized U powder of controllable quality are included. (arth)

Ceramics as a Creative Medium for Sixth and Seventh Grade Pupils

Description: In view of the fact that clay has not been used so extensively or wisely in elementary art education as the generally recognized importance of the material seems to justify, the purpose of this study is to explore the possibilities of clay as a creative medium and to determine which of the many ceramic techniques are most suitable for use by pupils in the upper elementary grade.
