topnik - Opis:
- Studies done on recycled products gained from computer boards have been presented. Alloys fabricated by melting of computer boards were investigated in detail. It was found that the alloy is segregated into two regions - copper and iron rich, in which other alloying elements, forming either solid solutions or intermetallic phases, are dissolved. Scale from melting and sediment from etching metals in hydrochloric acid were also studied. In the scale fluxing agents and residual of metals were gathered, whereas in the sediment some amount of noble metals was detected. Microscopic investigations and chemical composition measurements were performed on alloys from melted boards as well as on the scale and the sediment.
