개요Barium fluoride appears as colourless, odourless crystals/white powder and is slightly soluble in water but soluble in ethanol and methanol. When heated, barium fluoride decomposes and emits toxic fumes of fluorine and barium. Barium fluoride is used as a preopacifying agent and in enamel and glazing frits production. Its other use is in the production of welding agents (an additive to some fluxes, a component of coatings for welding rods and in welding powders). It is also used in metallurgy as a molten bath for refining aluminium.
용도Barium Fluoride is used in ceramic flux, carbon brushes for electrical equipment, glass making, in the manufacture of other fluorides, crystals for spectroscopy, electronics and dry-film lubricants. Barium Fluoride is used in spectroscopic components. Barium Fluoride is often suitable for applications in the passive IR band (8 to 14 m) and is often used as a viewport window for thermography.
