Resumo: We have computed the isospin and spin averaged cross sections of the processes pi K* -> rho K and rho K* -> pi K, which are crucial in the determination of the abundances of K* and K in heavy ion collisions. Improving previous calculations, we have considered several mechanisms which were missing, such as the exchange of axial and vector resonances (K-1(1270), K-2*(1430), h(1)(1170), etc.) and also other processes such as pi K* -> omega K
