An estimation of the interfacial energy of the copper-copper sulphate solution interface and of the specific surface of copper powder

Abstract

Apossible way for the estimation of the interfacial energy of the copper – copper sulphate solution interface is proposed. The estimated value of (2.7±0.3) J cm-2 and the derived equations which relate the specific surface of copper powder to the deposition conditions permit an estimation of the specific surface of copper powderc The agreement between the estimated value and literature data is very good.

Predložen je mogući način za procenu međupovršinske energije bakar – rastvor bakar sulfata. Procenjena vrednost od (2,7±0,3) J cm-2 i izvedene jednačine koje povezuju specifičnu površinu bakarnog praha i uslova taloženja dozvoljavaju procenu specifične površine bakarnog praha. Slaganje između procenjene vrednosti i literaturnih podataka je veoma dobro.
