說(shuō)明：粉色粉末，不溶于水，可溶于酸。極易吸潮，能迅速吸收空氣中的水份和  二氧化碳，應(yīng)置于密封容器內(nèi)。

用途：是氧化物電解法和鈣熱還原法制取稀土金屬及合金的重要原料,如氧化物電解法制取金屬用其氟化物作電解質(zhì)。此外氟化稀土還用作鋼鐵和有色合金的添加劑，改善鋼鐵的性能。

Description: pink powder, insoluble in water,  soluble in acid. Can easily absorb moisture, can quickly absorb moisture and carbon dioxide in the air, it should be kept in sealed containers.

Use: is an important raw material of rare earth metal and alloy oxide electrolysis and calcium thermal reduction method, such as oxide electrolysis method to take the metal with the fluoride electrolyte. The addition of rare earth fluoride is used as additive for steel and non-ferrous alloy steel, improve the performance of steel.
