We have studied the detailed structure and mechanical properties of the Nb2O5 and Ta2O5 pentoxides after ultrarapid quenching in comparison with the properties of Nb2O5 and Ta2O5 ceramics prepared by a conventional ceramic processing technique and using high-intensity light (HIL) in an optical furnace. The results demonstrate that high-energy processing (HIL and ultrarapid quenching) improves the hardness and strength of Nb2O5 and Ta2O5. At the same time, HIL processing and quenching lead to structural disordering of the Nb2O5 and Ta2O5 pentoxides.
