METHOD FOR PRODUCING METAL FLUORIDES Russian patent published in 2008 - IPC C01F17/00 C01D3/02 C01F5/28 C01F7/50 C01F11/22 B82B3/00 

Abstract RU 2328448 C1

FIELD: nanotechnology.

SUBSTANCE: invention relates to the method for producing the metal fluorides and comprises in the interaction of the gaseous hydrogen fluoride with the powder-like micron-sized compounds of the alkaline, alkali-earth and rare-earth metals, with producing the metal fluoride nanopowders. The hydrofluorination is performed at 150-200°C within 1-2 hours. As the compounds, the hydrides, nitrates and oxides of the said metals are used.

EFFECT: enables producing of subtle metal fluoride powders at lower temperature as compared to methods currently in use, and with less hydrogen fluoride consumption.
