Regularities of Changes in Physical Properties of Oxides with Perovskite-Type Structure During Modification
摘要
Table 3.1 provides a summary of the scheme, formulae, and quasi-chemical equationsQuasi-chemical equations, associated with cationic and vacancyVacancy modification of one of the SS of the (Na, Li)NbO3 system. The table illustrates the position of modifiersModifiers within the crystal latticeCrystal lattice of the matrix, as well as the nature and concentration of vacancies that have been formed. The SS of composition Na0.875Li0.125NbO3, situated at the Rh boundary of the MO of the (Na, Li)NbO3 system and exhibiting exceptional values of piezoelectric parameters (Reznichenko and Shilkina in Ser Phys 39(5):1118–1121, 1975; JTF 47:453–455, 1977), was selected as the subject of investigation.
