An infinitesimal decrease in temperature from Tc is enough for the phase separation process to occur within few seconds.
During the phase separation, the disturbance in the whole liquid was observed. This is due to convection or rapid migration of two phases in each other which might be due to buoyancy driven fluid flow.
The various possibilities for the occurrence of the miscibility gap in theliquid state have been reported .
The other reactions are concern with monotectic and eutectic.
The monotectic reaction can be represented as:
