Structural conditionality of the physical properties of the new representatives of the family of superprotonic crystals

Abstract

To reveal the effect of isomorphic substitution on the kinetics of phase transitions, single crystals of (K_1–x(NH₄)_x)mH_n(SO₄)_{(m + n)/2} · yH₂O solid solutions are grown from the K₃H(SO₄)₂–(NH₄)₃H(SO₄)₂–H₂O system. The chemical composition of the single crystals grown is determined by energy dispersive X-ray microanalysis. The thermal, optical and dielectric properties of (K_1–x(NH₄)_x)_mH_n(SO₄)_{(m + n)/2} · yH₂O single crystals are studied. The structural conditionality of the physical properties of these compounds is determined on the basis of the data of precision studies of the structure.
