Abstract

Phase formation in CaF2–HoF3 system has been studied by coprecipitation followed by X-ray powder diffraction. Aqueous nitrate solutions have been used as initial substances, while hydrofluoric acid has been employed as fluorinating agent. Formation of hydrated nanophases: solid solution Ca1–x Ho x F2 + x (х ≤ 0.1) and HoF3 has been revealed. Dehydration proceeds on heating to 600°C.
