The superconducting phase diagram of heavy-fermion UPt[sub 3] has been determined with the use of a sensitive dilatometric technique. Discontinuities observed in the coefficients of the linear thermal expansion ([alpha]) and magnetostriction ([tau]) at the phase lines yield the uniaxial pressure dependence of the various phases via the Ehrenfest relation. The results yield important constraints on the analysis within a Ginzburg-Landau approach.
