摘要： A melt-texturing method for producing high transition temperature superconducting ceramic elements of given length, such as wires of Y Ba.sub.2 Cu.sub.3 O.sub.7-.delta., which method is much faster and efficient than the existing ones. In this method, an element made of grains of superconducting ceramic precursor material is subjected to zone melting at a number of different locations equally spaced apart along its length. This multi-zone-melting is carried out at the same time, under the same temperature and speed conditions and in the same direction so as to form a same number of similarly textured zones along the length of the element, which zones grow up while the method progresses until they merge. This method makes it possible to multiply the present rate of production known to be very low, by a number of the same order of magnitude as the number of different locations where zone melting is carried out. If the number of locations is, say, 10, then the rate of production should be multiplied by approximatively the same number, 10.

摘要： A single phase superconducting oxide ceramic material in the form of highly oriented platelets, and a process for the production thereof. The process involves calcining in a non-reducing atmosphere a homogeneous mixture of stoichiometric proportions of suitable precursor materials. The calcination temperature is below the peritectic melt temperature of the superconducting material, and is at or above a temperature and for a time sufficient to effect partial melting of at least one of the precursor materials to a degree sufficient to effect diffusion of at least one of the precursor materials throughout the mixture. The calcination vessel is not wetted by melts of the precursor materials at the calcination temperature. The calcined material is then annealed in a non-reducing atmosphere. A typical material produced by the process is YBa.sub.2 Cu.sub.3 O.sub.x superconducting material, at a calcination temperature of about 976.degree.-982.degree. C.

摘要： The present invention generally relates to mechanisms for preventing undesirable oxidation (i.e., oxidation protection mechanisms) of reinforcement materials in composite bodies. The oxidation protection mechanisms include getterer materials which are added to the composite body which gather or scavenge undesirable oxidants which may enter the composite body. The getterer materials may be placed into at least a portion of the matrix such that any desirable oxidant approaching, for example, a fiber reinforcement, would be scavenged by (e.g., reacted with) the getterer. Ceramic filler materials which serve as reinforcements may have a plurality of super-imposed coatings thereon, at least one of which coatings may function as a getterer. The coated materials may be useful as reinforcing materials in ceramic matrix composites to provide improved mechanical properties such as fracture toughness. The present invention also relates to improved composites which incorporate these materials, and to their methods of manufacture.

摘要： A method of fabricating a superconducting ceramic pipe including the steps of: melting a ceramic powder having a predetermined composition to form a melt; filling a supporting tube with the melt by a suction caused by a vacuum pressure; partially solidifying an outer part of the melt near the tube to form a shell (i.e., a ceramic pipe); discharging an inner unsolidified part at the center of the tube from the tube by gravity, to form a solidified ceramic pipe on the inside surface of the tube; and heat treating the ceramic pipe to convert it into a superconducting pipe. When a supporting tube with a bottom plate is used, the melt is poured into the tube, and the tube is turned over to remove an unsolidified melt, whereby a superconducting ceramic pipe with a bottom is fabricated.

摘要： A process for preparing 123 superconductor material comprising heating a 123 compact in direct physical contact with a 211 compact to decompose only the 123 compact to form a liquid phase in the 123 compact is disclosed. The heat is maintained with the liquid phase passing into the 211 compact, to form a decomposed compact and an enriched compact. The decomposed and enriched compacts are cooled to below 1000 degrees celsius to promote a peritectic reaction between the 211 grains and the infiltrated liquid phase in the 211 compact. The decomposed and enriched compacts are then further cooled to about 400-600 degrees celsius in an oxygen atmosphere, and finally cooled to room temperature to yield a fused 123 decomposed compact-123 enriched compact. The 123 superconductor having enhanced electrical and mechanical properties is the 123 enriched compact which can be separated from the decomposed compact, by severing the 123 decomposed compact from the 123 enriched compact.

The device comprises two metal cylinders with parallel axes, which rotate in opposite directions and are cooled. The metal cylinders exhibit a corrugated surface, and an elevation on the surface of one cylinder in each case engages in the recess of the surface of the other cylinder with formation of a gap. The melt is poured into the gap, drawn by force and simultaneously cooled under pressure.

摘要： A fundamental pinning mechanism has been identified in the Bi-Sr-Ca-Cu-O system. The pinning strength has been greatly increased by the introduction of calcium- and copper-rich precipitates into the sample matrix. The calcium and copper are supersaturated in the system by complete melting, and the fine calcium and copper particles precipitated during subsequent crystallization anneal to obtain the superconducting phases. The intragrain critical current density has been increased from the order of 10.sup.5 A/cm.sup.2 to 10.sup.7 A/cm.sup.2 at 5 T.
