The present study was performed to verify whether a curious anomaly found out in the Zn–Bi system could occur in the Zn–Pb system. Three different methods of emf, sampling and picnometric techniques were employed to attain this purpose.
The obtained results proved that such anomaly occurred also in a like manner in the Zn–Pb system. Temperature dependences of the density behaved irregularly to be indicative of an existence of the structural transformation or local liquid separation in the molten alloys.
