Note that snapshots of the VTAnDeM GUI shown in Figure are an example of visualizing a quaternary material. The diagrams will look different for binary and ternary compounds however. For example, the slider in the first and second tabs (Figure ) will not exist for binaries and ternaries. In the second tab (Figure ), the three-dimensional representation of the phase stability region will be a plane for ternary materials (two independent and one dependent variable) instead of a solid for quaternary materials (three independent and one dependent variable). Accordingly, the competing compounds will form edges on planar phase stability regions for ternary materials instead of facets. In the third tab (Figure ), the compositional phase diagram will be a twodimensional triangle for ternary systems instead of a tetrahedron.
