In this paper, we consider a slab represented by the interval 0 < y < `, at the initial temperature< y < `, at the initial temperature v0(y) = M > 0 having a positive constant heat °ux q0 on the left face and a contact perfect condition, kvy(`; ¿ ) + Mf cf v¿ (`; ¿ ) = 0, on the right face y = `. We consider the corresponding heat conduction problem and we assume that the phase-change temperature is 00C. We obtain time estimates for the occurrence of a phase-change by means of Laplace Transform and Method of Lines.0(y) = M > 0 having a positive constant heat °ux q0 on the left face and a contact perfect condition, kvy(`; ¿ ) + Mf cf v¿ (`; ¿ ) = 0, on the right face y = `.
