From: How well suited are current thermodynamic models to predict or interpret the composition of (Ba,Sr)SO4 solid-solutions in geothermal scalings?

Lippmann diagram for (Ba,Sr)SO4 at 70 °C and 1 bar pressure. Highlighted by lines are the composition of the aqueous solution at the geothermal site (X (aq, exp) = 0.0045 ± 0.0007), and the expected solid composition according to the regular (dashed line) and ideal (dotted line) models. The arrow marks the beginning of the spinodal gap according to the Becker model (SPBecker)
