As exploratory methods of multivariate analysis, cluster analysis, principal components analysis, and two-way clustering were applied for a set of copper-lead and copper-zinc borate glasses. Specific correlations among the physicochemical properties of copper glasses were interpreted. In particular, the effect of Pb and Zn doping metal ion in copper glasses in the structural and mechanical properties is identified. Interestingly, the degree of lead content determines two kinds of glasses with specific physicochemical properties.6 p.application/pdfengcc-by (c) Dimitrov, Dimitar et al., 2020https://creativecommons.org/licenses/by/4.0/Química físicaBoratsPhysical and theoretical chemistryBoratesinfo:eu-repo/semantics/article7067212021-06-13info:eu-repo/semantics/openAccess
