Chapter 10, Problem 3RQ
- 3. A phase diagram for carbon and platinum is shown. Assuming the lines shown are linear, we can say the mixture has the following characteristics:
- Below 1700°C, it is a mixture of solid platinum and graphite.
- Above 1700°C, there are two possible phases: a liquid (L) phase and a liquid (L) + graphite phase. The endpoints of the division line between these two phases are labeled on the diagram.
Use the workbook provided to determine the phase of a mixture, given the temperature and carbon content.

- a. Write the equation to describe the temperature of the dividing line between the liquid (L) region and the liquid (L) 1 graphite region in column C. Reference the carbon content found in column B as needed. Add any absolute reference cells you feel are needed to complete this calculation.
- b. Write the conditional statement to determine the phase in column D. For simplicity, call the phases Pt + G, L, and L + G. For points on the line, YOU can decide which phase they are included in.

3. Platinum and gold are completely soluble in both the liquid and solid states. The melting point
of platinum is 3225°F and that of gold is 1945°F. An alloy containing 40% gold starts to solidify
at 2910°F by separating crystals of 15 percent gold in solid. An alloy containing 70% gold starts
to solidify at 2550°F by separating crystals of 37% gold in solid.
Draw the equilibrium diagram to scale on a piece of graph paper and label all points, lines and
areas.
For an alloy containing 70% gold (a) give the temperature of initial and final solidification.
(b) Give the chemical composition and relative amounts of the phases present at 2440°F.
