Effect of forced convection on the purification of metallurgical silicone by Direction solidification

Abstract: The effects of forced convection on the microstructure, macrostructure and macrosegregation of impurities in cylindrical ingots obtained by directional solidification of metallurgical grade silicon were examined. Two experiments were carried out, one without and another with the forced convection induced by a disk at the melt top rotating at Leia mais…

Aproveitamento de materiais de lâmpadas led: investigando os mecânicos de desmantelamento de lâmpadas do tipo bulbo

Resumo: A demanda da sociedade moderna por inovações tecnológicas, descarbonização e transição energética tem impulsionado o consumo de diversos metais como cobre, lítio, cobalto, níquel, elementos terras raras, além dos tradicionais ferro e alumínio. Estes metais são majoritariamente obtidos a partir de fontes primárias (jazidas minerais), no entanto, o desenvolvimento Leia mais…
