As per Step 2, the triangle/ternary diagram has then been stretched, so it looks like an equilateral triangle again, which doesnвЂ™t affect the XY coordinate system behind it, as it is stretched with it.Д¬orrespondingly, due to the projection of A to Y (100 units), a factor of 0.86603 comes into play: tan(30В°) = 0.57735 -> 0.57735 x 0.86603 = 0.5. 7).Д«ecause A is projected to 100 units (rather than 86.60вЂ¦), the triangle is elongated and the angle of 30 degrees changes to 26.56505 degrees unfortunately, Excel doesnвЂ™t plot diagrams in scale to show this.

The compositions on a ternary diagram must sum to unity if in mole or weight fractions, or to 100 if in percent. Made by faculty at the University of Kentucky and produced by the University of Colorado Boulder, De. A point having composition (A, B, C) on Figure 4.23 can be located anywhere on the ternary diagram and such a point represents the overall composition of the phase, regardless of the number of phases. Thus, we can use the normalized A component as Y without a trigonometric function (Fig. Develops a ternary phase diagram using equilibrium data. The ternary diagram ABC is projected into a cartesian XY graph.ДЇor an equilateral triangle with a side length of 100 units (e.g., X-axis B-C side 0-100%), the height is 86.60254 units (i.e., Y-axis A).ДЄ is projected onto Y with 100 units. In the case here, however, it is a different approach: You are right with the tan(30В°) statement for calculating the X coordinate in an equilateral triangle/ternary diagram.
