摘要

To elucidate the effect of isomorphic substitution on the kinetics of phase transitions, single crystals of (K_x(NH_4)_(1–x))_mH_n(SO_4)_((m + n)/2) ? yH_2O solid solutions are grown from the K_3H(SO_4)_2–(NH_4)_3H(SO_4)_2–H_2O system, whose end members are known to undergo superprotonic phase transitions of fundamentally different kinetics. The chemical composition of the single crystals grown is determined by energy dispersive X-ray microanalysis. The thermal and optical behavior of (K,NH_4)_9H_7(SO_4)_8 ? H_2O single crystals is studied in the temperature range 295–420 K and the crystal structure at 295 K is determined. A comparison of the results of the studies with data for crystal K_9H_7(SO_4)_8 ? H_2O published earlier shows that the substitution of ammonium for potassium atoms lowers the temperature of the structural phase transition by 8 K.
