- Abstract
- It has been established that the solid solutions (SS) of the system (1-x)(Na0.5K0.5)NbO3-xPb(Ti0.5Zr0.5)O3 have optimal properties, when they are obtained not from the precursors (synthesized uttermost components), but from initial raw materials (oxides and hydrocarbonates). Using of mechanical activation improves the quality of ceramics in SS with 0.6 ≤ x ≤ 0.8; using of thermally treated Nb2O5 turned out to be undesirable because of the negative effect on the sintering properties of ceramics. By the technological process optimizing SS are obtained that are promising for using in devices operating in the low and mid-frequency ranges, microwave technology.
