Formation of a new solid phase on cooling a binary two phase aggregate comprising a solid and liquid is termed as peritectic transformation. Except for the grain refinement of a few Al-based alloys, the technological application of peritectic transformation has so far been limited. However, the recent method of synthesizing the superconducting YBCO-compounds through peritectic transformation necessitates a better understanding of the mechanism and kinetics of this liquid {yields} solid transformation. In this paper, a simple mathematical model on the kinetics of peritectic transformation has been proposed and its predictions have been compared with the experimentally determined data from the Cd-Ag system. It may be noted that the kinetic data on isothermal peritectic transformation in the Cd-Ag system, which yields excellent microstructures for kinetic analysis, have not been reported earlier.
