Abstract

O PRESENTE PEDIDO ESTÁ RELACIONADO COM UM NOVO TIPO DE ALVOS DE ESPALAÇÃO DE CARBONETOS DE URÂNIO, CONSTITUÍDO POR MATERIAIS DE CARACTERÍSTICAS POROSA E NANOESTRUTURADA, COM UM TAMANHO DE GRÃO ENTRE OS 2 E OS 100 NM.É OBJETO DO PRESENTE PEDIDO O PROCESSO DE PRODUÇÃO DE MATERIAIS DE CARBONETOS DE URÂNIO, CONSTITUINTES DE UM ALVO DE ESPALAÇÃO, QUE SE BASEIA NA TÉCNICA DE ELETROFIAÇÃO PARA A PRODUÇÃO DE FIBRAS POLIMÉRICAS COM URÂNIO. ESTAS, SÃO DE SEGUIDA DECOMPOSTAS SOB UMA ATMOSFERA CONTROLADA E A UMA DADA TEMPERATURA, SENDO OS MATERIAIS RESULTANTES DA DECOMPOSIÇÃO (11), AQUECIDOS A TEMPERATURAS ENTRE OS 1400º C E OS 2400º C, SOB VAZIO OU ATMOSFERA INERTE, DURANTE UM PERÍODO DE TEMPO ENTRE 1 E 24 HORAS. COMO RESULTADO, OBTÉM-SE UMA MISTURA DO TIPO UCX-C-UOY DE FINA GRANULOMETRIA, QUE DÁ ORIGEM A ALVOS DE ESPALAÇÃO QUE APRESENTAM MELHOR ESTABILIDADE E RENDIMENTO NA PRODUÇÃO DE ISÓTOPOS.THIS ORDER IS RELATED TO A NEW TYPE OF URANIUM CARBON SPALING TARGETS, CONSTITUTED BY MATERIALS OF POROUS AND NANOSTRUCTURED CHARACTERISTICS, WITH A GRAIN SIZE BETWEEN 2 AND 100 NM. THE OBJECT OF THIS ORDER IS THE PRODUCTION PROCESS OF PRODUCTION URANIUM CARBON MATERIALS, CONSTITUTING A SPALING TARGET, BASED ON THE ELETROPHYING TECHNIQUE FOR THE PRODUCTION OF POLYMERIC FIBERS WITH URANIUM. THESE ARE THEN DECOMPOSTED UNDER A CONTROLLED ATMOSPHERE AND AT A GIVEN TEMPERATURE, THE MATERIALS RESULTING FROM THE DECOMPOSITION (11), HEATING AT TEMPERATURES BETWEEN 1400º C AND 2400º C, UNDER EMPTY OR INERT ATMOSPHERE FOR A PERIOD OF TIME AND 24 HOURS. AS A RESULT, A MIXTURE OF THE UCX-C-UOY TYPE OF FINE GRANULOMETRY IS OBTAINED, WHICH GIVES SPALATION TARGETS THAT PRESENT BETTER STABILITY AND PERFORMANCE IN ISOTOPE PRODUCTION.
