Abstract

We present the results of the thermodynamic theory of piezoelectric ferroelectrics and of the phenomenological theory of thermodynamic characteristics of the KH₂PO₄ type ferroelectrics. Available experimental data for the dielectric, piezoelectric, and elastic characteristics of the KH₂PO₄ type ferroelectrics and NH₄H₂PO₄ type antiferroelectrics are described using the proposed microscopic theory of these crystals. Using the results of the thermodynamic theory and experimental data we calculate the dielectric, piezoelectric, and elastic characteristics of the K_1-x(NH₄)_xH₂PO₄ type systems.
