What is pseudo ternary phase diagram?
Pseudo ternary phase diagrams are used to determine the region of microemulsion. existence. The effect of various surfactant/co-surfactant weight ratios on the extent of a stable microemulsion area can easily. be observed with these diagrams.
How do you read a pseudo ternary phase diagram?
Reading Ternary Diagrams
- Locate the 1 (or 100%) point on the axis.
- Draw a line parallel to the base that is opposite the 100% point through the point you wish to read.
- Follow the parallel line to the axis.
- Repeat these steps for the remaining axes.
How does a ternary diagram work?
A ternary plot is a triangular plot of three variables which must sum to a constant value, e.g. 1.0 or 100% (Howarth, 2009). In most cases the ratios of the three variables are plotted as points on an equilateral triangle (West, 1982). There are two ways of plotting data in ternary graphs.
What is ternary phase diagram?
Ternary Phase Diagrams A ternary phase diagram shows possible phases and their equilibrium according to the composition of a mixture of three components at constant temperature and pressure. Figure 4.23 shows a schematic of a ternary phase diagram.
What is Cosurfactant?
: a chemical substance that is used in addition to a surfactant to improve its performance especially : a second surfactant that is used in conjunction with a primary surfactant.
What do you mean by ternary diagram?
A ternary diagram is a triangular coordinate system; the edges of the triangle are the axes. Ternary diagrams are used to plot three dependent variables that always add up to a fixed value, for example, to visualize the compositional variations of rocks or minerals.
What is the use of ternary phase diagram?
A ternary phase diagram shows possible phases and their equilibrium according to the composition of a mixture of three components at constant temperature and pressure.
What is microemulsion method?
The microemulsion technique promises to be one of the versatile preparation method which enables to control the particle properties such as mechanisms of particle size control, geometry, morphology, homogeneity and surface area.
How is a ternary diagram a pseudoternary diagram?
Even so, a pseudoternary diagram is still a useful way to represent some complex phase-behavior concepts that are not so easily visualized otherwise. A ternary diagram represents phase behavior at a constant temperature and pressure. Fig. 1 is a traditional pseudoternary-diagram representation of phase behavior for the pseudo-components: C 1
How are the three phases of a ternary system represented?
According to the phase rule, three phases may coexist at a fixed temperature and pressure for some ternary systems. Fig. 5 shows the general structure of such systems. The three-phase region (3 Φ) on a ternary diagram is represented as a triangle in Fig. 5.
Where are the tie lines in the ternary phase diagram?
In Figure 4.23, a single three-phase region exists and is given by the triangle in the center of the diagram. There are no tie lines for the three-phase region since compositions are given by the vertices of the small triangle in the center of the diagram.
How is the phase of a mixture represented in a ternary diagram?
Ternary phase diagrams represent the phase behavior of mixtures containing three components in a triangular diagram. Phase behavior of mixtures containing three components is represented conveniently on a triangular diagram such as those shown in Fig. 1.
