Phase formation processes in the Ta2O5-Nb2O5 system have been precised and the phase diagram has been constructed for the system. No compounds are found in the system; a peritectic is observed having the composition Ta2O5 (48 %mol.)-Nb2O5 (52 %mol.) Optical and dielectric properties of the system thin films have been studied studied.
