Abstract

fetched live from OpenAlex

Cobre refinado a fogo (FRHC) possui diversas aplicações, principalmente na produção de fios e cabos elétricos; metal com alto teor de impurezas, especialmente de oxigênio, cuja elevada concentração de impurezas pode afetar as propriedades do material. Dentre as propriedades, sobressai a alta condutividade térmica e elétrica. Este artigo tem como objetivo realizar uma prospecção científica e tecnológica sobre a influência das impurezas nas propriedades do cobre, a fim de compreender os efeitos provocados durante os processos de fabricação de fios e cabos. A metodologia utilizada é uma revisão bibliométrica, tomando como bases científicas Web of Science e ScienceDirect is Elsevier’s, para busca de artigos, e um mapeamento patentário na plataforma do EPO e Google Patents. Como resultados, 34 artigos e 13 patentes relacionadas, sendo perceptível nos últimos anos a falta de evolução e inovação de novos métodos e tecnologias de refino de cobre, principalmente voltados para a contenção de impurezas, com tendências China, Estados Unidos, Austrália, Polônia, Canadá, Reino Unido e Alemanha. Palavras-chave : Cobre (FRHC). Impurezas. Oxigênio. Propriedades. ABSTRACT Fire-refined copper (FRHC) has several applications, mainly in the production of electrical wires and cables; metal with a high content of impurities, especially oxygen, whose high concentration of impurities can affect the properties 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 impurities 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 related patents were obtained, being noticeable in recent years, the lack of evolution and innovation of new methods and technologies for refining copper, mainly aimed at containing impurities, with trends in China, the United States, Australia, poland, canada. United Kingdom and Germany. Keywords : Copper (FRHC). Impurities. Oxygen. Properties.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
