We have investigated the quantum-to-thermal crossover temperature T* for cavitation in liquid-helium mixtures up to 5% concentrations. With respect to the pure- case, is sizeably reduced, to a value below 50 mK for concentrations above 2%. As in pure , the homogeneous cavitation pressure is systematically found close to the spinodal pressure.
