METHOD FOR PRODUCING METAL FLUORIDES

摘要

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. ^ 5 cl, 5 dwg, 2 tbl
