2. Construct a hypothetical binary phase diagram of a system consisting S and T as components. Clearly labeled the X and Y axis, as well as each phase field. The followings are the conditions of the phase diagram: (1) Pure S and T have melting temperatures of 1800 and 1550 C, respectively. (2) Compound S2T3 melts congruently and has melting points of 1450 C. Compound ST melts incongruently at 1400 C. (3) A maximum of 15% of T is soluble in S:Ts forming the solid solution a (4) A eutectic exists between a (ss) and T at 1300 C and another eutectic exists between S:T and ST3 at 1300 C.
