Ternary triangular plot phase diagrams

Chemistry Software Download


In chemistry Ternary Diagrams are used for depicting chemical compositions - phase diagrams. These diagrams are three-dimensional but is illustrated in two-dimensions for ease of drawing and interpretation. In ternary diagrams the relative percentage (normally weight %) of three components are represented by A, B and C. The only requirement is that the three components have to sum to 100%. If they don't, you have to normalize them to 100%

Data Entry

Both the symbol and text can be inserted in CHEMIX ternary diagrams. A and B can only be inserted as % (e.g.0-100). Text fragments in which may follow the numbers A and B must only partly contain numbers e.g. 10 10 L1 where L1 is the text fragment.

Data entry commands

The case sensitive commands that can be inserted at the end of each text string, are:
 = hide text
[_???]  = Angled text in degrees e.g. [_180]    (180 deg).
Font sizes:
 = small font
[bf] = big font
 = huge font
[gf] = gigantic font

Font colors: (Black default color)
  = white font
   = red font
   = green font
   = blue font
   = cyan font
   = fuchsia font
   = yellow font

Font style:
[tf]  = thick font(bold) font
 italic font
 underlined font


[-s] = hide symbol

Symbol sizes:
 = small symbol
[ms] = medium symbol
[bs] = big symbol

Symbol colors:
[Ws]  = white symbol
   = red symbol
   = green symbol
   = blue symbol
   = cyan symbol
   = fuchsia symbol
   = yellow symbol
[BS]   = black symbol (both capital letters)

Symbol change:
[1s]  = circle symbol
   = square symbol
   = diamond symbol
   = triangle symbol
   = cross symbol
   = ring/hollow circle symbol

Misc. commands:
 = ignore hide (will ignore a "global" check box hide if  Hide Text/Symbols- has been selected).
 = ignore limits - This command enables you to put text or/and symbols outside the triangular frame.

-5 -5 Text outside frame[il]         Text placed outside the triangular frame (A = -5%     B = -5%)

Text Insertion: Insert two numbers A% and B% and text representing a phase (e.g. L1) separated by spaces. Because L1 is not a number it will be identified as text in which always must be placed after the two numbers A and B e.g. 5.2  7.3  L1 (A= 5.2 B=7.3 Text=L1).

Identify a number as text: A number can be identified as text if it is enclosed in square brackets or connected to text without space between text and number e.g "number10" .

25 25 number[11]       --> number 11 (default font)
30 30 number12         -->   number12 (default font)

Text Insertion: Insert two numbers (A and B normally weight %) and text representing a phase (e.g. L1) separated by spaces. Because L1 is not a number it will be identified as text in which always must be placed after the two numbers A and B e.g. 20 35 L1 (A=20% , B=35% Text=L1).
Negative numbers are not allowed. C will be calculated as C=100%-A-B. The sum (A+B) must not exceed 100%.

Calculate: After inserting or changing the content in the A(%) B(%) Text-field, you have to re-calculate


Normalization: This is a way to convert e.g. A  B  C   into  A%  B%. Before normalization make sure that data has been inserted in A B C format. Normalization will change inserted A B C values into A and B percent values.


Below: Sample normalization: Converting 5 points in A B C format into A% B% format. 

 A          B           C
0          2.25       35.25 
2.85     1.54     24.11
6.90     1.66     25.94
7.92     1.11       17.37
15.24   1.37     21.53

As we see below these values vill be converted into A% B% format:

  A%       B%
0.00         6.00
10.00      5.40
20.00      4.81
30.00      4.20
39.96      3.59

Spline mode and Fill mode

Spline mode

Splines: By selecting spline mode you will be able to create splines. Spline points may be created interactively by clicking the mouse pointer (cross) within the triangular/frame area (making small rectangles). The first and the last spline point may be connected by selecting connect. You may move spline points by hand. Simply locate the mouse pointer within a small rectangular area, click the left mouse button and move the mouse pointer/rectangle. Spline points may be removed by clicking the right mouse button with the mouse pointer located within a rectangular area. A thick-lined rectangle/(spline point) indicates that the spline point belongs to the currently selected set of spline points (1 spline 2 spline). Also, every set of spline points has a number located on the right side of the first created spline point. This number is the spline set number. 30 independent sets of splines each containing up to 50 spline points may be selected/created from the splines drop-down selection box.

Spline options

Fill mode

Fill mode enables you to insert fill points. First select a color from the drop down selection box. Insert a fill point by clicking left mouse button inside the frame. Fill points can be moved around inside the frame using left mouse button. You can remove fill points (cross) by locating the mouse cross inside a fill-point and right-click it. You can also remove a fill point by the Delete push button.  

Fill options
