制备方法与用途

氟化镨(III)概述

氟化镨(III)主要用于光学镀膜、光纤掺杂、激光晶体、单晶原料、激光放大器以及催化助剂等。

理化性质

氟化镨为淡绿色晶体或粉末，不溶于水，难溶于盐酸、硝酸和硫酸，但能溶于高氯酸。在空气中具有吸湿性，较为稳定。它广泛应用于实验室试剂、光纤掺杂、激光材料、荧光发光材料、光导纤维、光学镀膜材料以及电子材料等领域。

用途

• 制取金属镨：用于提取金属镨。
• 电弧碳棒添加剂：作为电弧碳棒的添加成分。
• 真空沉积：适用于真空沉积过程。

生产方法

1. 将50～100毫克Pr6O11置于镍反应室的小铂舟中，通入干燥氮气赶走空气和水蒸气。随后缓慢通入氯氟化三氯(ClF3)，在室温下进行反应。反应结束后，再通入氮气清除未反应的氯氟化三氯。用高价氧化物Pr6O11或PrO2进行上述反应也能产生氟化镨。
2. 将硝酸镨盐溶解于95%乙酸中，缓慢加入40%氢氟酸直到沉淀完全。

A facile template-free synthetic route was developed for one step, high yield, and large scale synthesis of ternary NH4Ln2F7 (Ln = Y, Ho, Er, Tm, Yb, Lu) nanocages. On the basis of our studies, these nanocages are thermodynamically stable forms of this group of NH4Ln2F7 compounds. The tendency

The closed-system furnished two unique features: (1) the hydrogen generated in the fluorination maintained a strong reducing atmosphere that permitted isolation of otherwise difficulty obtainable fluorides of lower oxidation
