Abstract

"MéTODO DE FABRICAçãO DE MATERIAIS SUPERCONDUTORES EMPREGANDO REDUçãO ELETROLìTICA E INFILTRAçãO". Um pré-formado (28) é fundido por moldagem ou estampado, a partir de um composto de metal ou de uma mistura de compostos de metal, sinterizada em ar, vácuo, ou gás inerte, e é eletroliticamente reduzido em um banho (20) de sal fundido, para formar um produto de metal ou de liga, poroso. A liga está na forma de uma esponja sólida, porosa. No banho (20), o sal está em contato com um reservatório (26) de material de infiltração fundido (24). Após finalização da redução eletrolítica, o produto poroso é passado para o interior do material de infiltração, o qual preenche os poros daquele, deslocando o sal. O produto infiltrado é, então, solidificado para processamento ulterior do material. De preferência, o material de esponja compreende nióbio, e o líquido de infiltração é, por exemplo, estanho em fusão. A esponja de nióbio infiltrada pode ser ulteriormente processada para formar um material de supercondutor do tipo A-15, por exemplo, Nb~ 3~Al e Nb~ 3~Sn."METHOD FOR MANUFACTURING SUPERCONDUCTIVE MATERIALS USING ELECTROLYTIC REDUCTION AND INFILTRATION". A preform (28) is cast or stamped from a metal compound or a mixture of metal compounds, sintered in air, vacuum, or inert gas, and is electrolytically reduced in a bath (20). of molten salt to form a porous metal or alloy product. The alloy is in the form of a solid, porous sponge. In the bath (20), the salt is in contact with a reservoir (26) of molten infiltrating material (24). After completion of the electrolytic reduction, the porous product is passed into the infiltrating material, which fills the pores of the infiltrate, displacing the salt. The infiltrated product is then solidified for further processing of the material. Preferably, the sponge material comprises niobium, and the infiltrating liquid is, for example, melt tin. The infiltrated niobium sponge may be further processed to form an A-15 superconducting material, for example Nb-3-Al and Nb-3-Sn.
