Partial molar densities of oxides in natural silicate melts can be estimated to useful precision by exploiting their strong correlation with densities of the corresponding solid oxides, reflecting the close structural similarity between silicate solids and silicate melts. Using this extrapolation method, partial molar density (in grams per mole-cubic centimeter at 1400 °C) is inferred to be 2.0 for SO 3  and 2.3 for P 2 OS; i.e., the partial molar volumes, V i, m(in cubic centimeters per mole), are 40 and 61, respectively. The inferred d V i,m /dT (in cubic centimeters per mole-kelvin) are 0.0056 for SO 3  and 0.0085 for P 2 OS 5.  Analogous estimates are also given for V 2 O 5 , Cr 2 O 3 , V 2 O 3 , ZrO 2 , La 2 O 3 , Ce 2 O 3 , and Nd 2 O 3 . The inferred uncertainty for the V i,m  estimates is 12% (1σ, relative), although the V i,m  for Cr 2 O 3  is somewhat more uncertain because on melting, this oxide probably changes from octahedral to largely tetrahedral coordination.
