Electrical Conductivity

When you open the Properties Combo Box you select the property of the electrolyte you want to be drawn, the electrical conductivity, for instance in the next figure.

Properties Combo Box

Temperature Icon Graphs (Input Superheat)

Compared to the Liquidus Temperature Diagrams Window the Electrical Conductivity Diagrams Window shows in addition to the concentration the temperature icon graphs. If you selected Input Superheat on the Electrolyte Composition/Properties Page AlPrg creates the electrical conductivity vs. superheat (ΔT) and the bath temperature vs. bath composition icon graph (T_B=f(AlF₃), for instance).

Icon Graphs: ElCond=f(ΔT) and T_B=f(AlF₃)

Icon-Plots: ElCond=f(deltaT) and Tb=f(AlF3)

Remark:
The Liquidus Temperature Combo Box is blocked to the equation of Solheim. This happens when the Electrolyte Property Diagrams Window is open and other properties than the liquidus temperatur (electrical conductivity in the figure) are drawn. If you want that AlPrg uses other liquidus temperature equations in the Electrolyte Composition/Properties Page you must close the Electrolyte Property Diagrams Window. AlPrg creates Electrolyte Property Diagrams other than the liquidus temperature only with the liquidus temperature equation of Solheim.

When you select the electrical conductivity vs. superheat icon graph (ΔT) the property diagram shows how the electrical conductivity depends on the electrolyte temperature if the superheat changes from -50 °C to +50 °C at constant liquidus temperature (see Theory: Liquidus Temperature Equ. 1). You can change the value of the superheat (ΔT) by a dragging action on the property diagram.

Property Diagram: ElCond=f(ΔT)

When you select the bath temperature vs. composition icon graph (T_B=f(AlF₃) the property diagram shows how the bath temperature depends on the selected bath component (aluminum fluoride in this case). If you change the aluminum fluoride concentration on the property diagram, AlPrg calculates a new liquidus temperature and bath temperature. AlPrg updates according to these new values all the other icon graphs.

Property Diagram: T_B=f(AlF₃)

If you had selected the electrical conductivity vs. alumina icon graph when you select the bath temperature vs. composition icon graph (T_B=f(AlF₃) the property diagram shows how the bath temperature depends on the selected bath component (aluminum fluoride in this case). If you change the aluminum fluoride concentration on the property diagram, AlPrg calculates a new liquidus temperature and bath temperature. AlPrg updates according to these new values all the other icon graphs.

Temperature Icon Graph (Input Electrolyte Temperature)

If you selected Input Electrolyte Temperature on the Electrolyte Composition/Properties Page AlPrg creates the electrical conductivity vs. electrolyte temperature icon graph.

Icon Graph: ElCond=f(T_B)

The icon graph and the property diagram of electrical conductivity vs. electrolyte temperature show the region where you can modify the electrolyte temperature (by dragging, for instance) namely liquidus temperature ± maximal superheat (T_B±50 °C).

Property Diagram and Icon Graph: ElCond=f(T_B)

If you select another electrical conductivity equation (of L. Wang, for instance) it may happen that the relation contains no potassium fluoride dependence the corresponding the property and icon graph are grayed.

Property Diagram and Icon Graph: ElCond=f(KF)

If you choose however Input Superheat on the Electrolyte Composition/Properties Page the electrical conductivity depends on potassium fluoride because in this case AlPrg determines the bath temperature from the liquidus temperature that depends on potassium fluoride. Consequently the potassium fluoride property and icon graph are NOT grayed.
