Web12 apr. 2024 · A binary two-phase system has two degrees of freedom. At a given T and p, each phase must have a fixed composition. We can calculate the liquid composition by rearranging Eq. 13.2.4: xA = p − p ∗ B p ∗ A − p ∗ B The gas composition is then given by yA = pA p = xAp ∗ A p = ( p − p ∗ B p ∗ A − p ∗ B)p ∗ A p.

Web24 mrt. 2024 · Summary In this chapter, we review phase diagrams of alkali and alkaline earth carbonates at high pressures, particularly simple, binary, and ternary systems, which were recently constrained at pressures of 3 and 6 GPa. These studies revealed a number of new alkali-alkaline earth double carbonates. WebPhase (or stability) diagrams are used to illustrate the conditions under which certain minerals are stable. They are graphs that show the limiting conditions for solid, liquid, and gaseous phases of a single substance or of a mixture of substances while undergoing changes in pressure and temperature or in some other combination of variables.
