Prospectivo da Influência das Impurezas nas Propriedades do Cobre Refinado a Fogo (FRHC)

Abstract

Fire-refined copper (FRHC) has several applications , mainly in the production of electrical wires and cables; metal with a high content of impu rities, especially oxygen, whose high concentration of impurities can affect the properti es of the material. Among the properties, the high thermal and electrical conductivity stands out . This article aims to conduct a scientific and technological survey on the influence of impuri ties on copper properties. The methodology used is a bibliometric review based on Web of Science and ScienceDirect is Elsevier's scientific bases, to search for articles , and patent mapping on the EPO and Google Patents platform. As a result, 34 articles and 13 r elated patents were obtained, being noticeable in recent years, the lack of evolution a nd innovation of new methods and technologies for refining copper, mainly aimed at c ontaining impurities, with trends in China, the United States, Australia, poland, canada. Unite d Kingdom and Germany.
