Abstract: Reactions of barium nitrate water solutions with hydrofluoric acid were studied. Barium hydrofluoride BaF$_2$ $\cdot$ HF is the product of reaction at any ratio and concentrations of initial solutions. Barium fluoride BaF$_2$ is formed under using of NH$_4$F as precipitate agent and as a result of interaction of BaCO$_3$ with HF solution. SEM and XRD analysis were used for characterization of phase composition and morphology of particles.

Keywords: nanofluorides, barium fluoride, barium hydrofluoride.
