Density of liquid copper





2003

Hello everyone,

I am working in a project as a graduate student and I desperately need to know what is the density of pure copper in the liquid phase. It is not necessary to get the exact number.

Thank you in advance.

For a good approximation, I would suggest you use the density of solid copper (8.933 g/cm3)

From "Chemical Engineers Handbook" [affil link on Amazon], 7th Edn., Table 2-119. Densities (Kg/m3) of Selected Elements as a Function of Temperature: Some values for copper:
Cu(s): 8930 at 300 K, 8686 at 800 K, 8458 at 1200 K.
Cu(l): 7920 at 1400 K, 7600 at 1800K. Extrapolates to 7955 at 1356 K (melting point).

Thanks, Ken! I thought Trevor's answer was excellent, but there is much more thermal expansion than my gut allowed for.

The density of molten copper at 1200 °C is near 7,898 g/cm3.
