What does the triangular diagram represents? Note that AKF diagrams are used for CaO-poor, K2O-rich rocks, whereas ACF diagrams should be used for Al2O3 and CaO – rich rocks. For each substance, the conditions defining the critical point are the critical temperature, the critical pressure, and the critical density.ĪKF Diagrams Minerals are plotted in the same way as was done for the ACF diagrams, and an example AKF diagram showing the potting positions of common metamorphic minerals is shown below. when p = 2 the sequence is called the binary expansion when p = 3, it is the ternary expansion.Ĭritical point, in physics, the set of conditions under which a liquid and its vapour become identical (see phase diagram).When p = 10, the sequence is just exactly the decimal expansion. At this point, the equilibrium phases become coincident and no separation can be made at that point. The Plait Point P, is the intersection of the raffinate-phase and extract-phase boundary curves.
The pseudoternary phase diagrams were constructed by water titration method (fig. How do you draw a pseudo ternary phase diagram? Ternary system CSA+OPC+additional CŠ When additional calcium sulphate is added to a blend of CSA and OPC more ettringite crystals are formed i.e. What are the two primary ternary systems existing for cement? What does the triangular diagram represents?.What is critical point in phase diagram?.
