说明：粉色粉末，不溶于水，可溶于酸。极易吸潮，能迅速吸收空气中的水份和 二氧化碳，应置于密封容器内。 用途：是氧化物电解法和钙热还原法制取稀土金属及合金的重要原料,如氧化物电解法制取金属用其氟化物作电解质。此外氟化稀土还用作钢铁和有色合金的添加剂，改善钢铁的性能。 | 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. |
