Circular solid state reduction process of fine copper powder synthesis with life cycle assessment for photovoltaics application

This paper presents the process of synthesis copper powders obtained by pyrometallurgical method without participation liquid phase. is based on simultaneous decomposition and reduction (II) carbonate. Hydrogen was used as a reducing agent. Due to strongly exothermic thermal effect reaction, mixture inert gas hydrogen better control parameters. Studies have shown that carbonate enables with narrow distribution controlled size. The size grinding time An life cycle assessment circularity study evaluate sustainability new process, focus given energy efficiency.
