Webb4 jan. 2024 · Theoretical Models Describing the Density of Lead-Free Solders. Density is a common physical property associated with all the metals and non-metals in solid and liquid states. Density is an essential factor when selecting a solder as it directly adds to the weight of the component. Hence, low-density materials are preferable for solder alloys. WebbThe highest recoverable energy density (Wrec) ~ 1.20 J/cm³ and energy-storage efficiency (η) ~ 72% were attained at 120 kV/cm for BNKTBZ-2FN ceramic with the excellent …
