Congruent melting occurs during melting of a compound when the composition of the liquid that forms is the same as the composition of the solid. It can be contrasted with incongruent melting. This generally happens in two-component systems. To take a general case, let A and B be the two components and AB a stable solid compound formed by their chemical combination. If we draw a phase diagram for the system, we notice that there are three solid phases, namely A, B and com… WebThe Bridgman technique requires a two-zone furnace. The materials which melt congruently do not decompose before melting and those do not undergo phase transformation between the melting point and room temperature can be grown as single crystal by Bridgman technique. WebThe thermal analysis is more commonly used for: (i) Drawing the liquidus, if under-cooling, or overheating is not large as well as heat of the phase change is not too small, when detection becomes difficult. (ii) For isothermal reactions. skin tune vegan cover cushion #01 fair tune
