The controlled decomposition of solid solutions in the vicinity of interphase boundaries separating domains of the coexisting antiferroelectric and ferroelectric phases opens new fields of applications for these materials. The lead zirconate–titanate based solid solutions are considered as an example of substances suitable for creation of materials with the negative refractive index. Manufactured composites constitute a dielectric antiferroelectric matrix with a structure of conducting interphase boundaries separating domains of the ferroelectric and antiferroelectric phases. The electric conductivity of the interphase boundaries occurs as a result of the local decomposition of the solid solutions in the vicinity of these boundaries. The decomposition process and consequently the conductivity of the interphase boundaries can be controlled by means of external influences.

用于制造新材料的铁电相和反铁电相共存的固溶体

在分离共存的反铁电相和铁电相的域的界面边界附近固溶体的受控分解为这些材料开辟了新的应用领域。锆酸铅-钛酸铅基固溶体被认为是适用于制造负折射率材料的例子。制造的复合材料构成具有导电相间边界结构的介电反铁电基体，将铁电相和反铁电相的域分开。界面界面的导电性是这些界面附近固溶体局部分解的结果。
