Abstract
Study of the CaF2–YF3 system by co-precipitation from aqueous nitrate solutions revealed the formation of Ca1−xYxF2+x solid solution precipitate containing up to 20 mol. % yttrium fluoride (x ≤ 0.2). A higher yttrium to calcium ratio in the starting solutions caused additional precipitation of orthorhombic β-YF3 nanophase elongated along the ⟨b⟩ axis. Cubic (H3O)Y3F10 phase was also formed (SSG Fm3m, a = 11.60 ˚A, KY3F10 structural type).
