Abstract

Mixed crystals (NH₄)₂Ni_xCo_{1 –}_x(SO₄)₂ · 6H₂O have been grown from aqueous solutions of different compositions by reducing the solution temperature in two growth regimes: static and dynamic. The optical characteristics of crystal samples are analyzed, the dehydration temperatures are measured, and the defect structure of the crystals is studied.
