Question

3. (15 pts) Bi and Te.form the solid compound i2Te which melts congruently at about 600 c. Bi and Te melt at 300 and 450*C resperiveiy. Solid BiTe, is partially miscible at all 'temperatures with solid ai and is also partiaily miscible with solid Te at all temperatures . a) What is congruent melting? sto scale) the Bi-Te solid-iquid phase diagram and labe all regions. the cooling-curve for the liquid mixture that is 65%-rich in Te. b) Skete c) Sket,

Answer 1

a) Congruent melting : it is actually the melting of solids in such a way that the composition of the resultant liquid remains the same as was in melting solid. Congruent melting point shows definite temperature of a compound.

For b) and c) : need more information
