(b) Using the similar phase diagram as shown in Figure 4, the MgO-65 wt% FeO ceramic is now solidified under the equilibrium condition. Evaluate (i) the composition of the last liquid to solidify (ii) the phase(s) present, the composition of the phase(s) and the amount of the phase(s) at 1800 C Temperature (C) 3000 2000 1000 ******** S=(Mg, Fe)0) 60 MgO 20 40 Weight percent Fe0 L 80 FeO Figure 4: The equilibrium phase diagram for the Nb-W system. The dotted curve shows a nonequilibrium solidus. (b) Using the similar phase diagram as shown in Figure 4, the MgO-65 wt% FeO ceramic is now solidified under the equilibrium condition.
