Phases, Microstructure, Dielectric and Piezoelectric Properties of Solid Solutions of the NaNbO_3 System - CuNb2O6 Prepared From Nb_2O_5 of Various Qualifications

摘要

It is established that the physicochemical state of niobium pentoxide of various qualifications influences the properties of solid solutions of the binary system NaNbO_3 - CuNb_2O_6. The article shows, that for practical purposes it is possible to use technical Nb_2O_5. Moreover, it shows that solid solutions with a relatively low dielectric constant, high sound speed and mechanical quality can be used as the basis of materials intended for operation in microwave devices.
