氟化氢铵氟化法制备稀土氟化物工艺研究

Preparation of Rare Earth Fluoride by Fluorination with NH_4HF_2

采用正交试验法,研究了用氟化氢铵作氟化剂直接与稀土氧化物(Gd2O3)反应,制备稀土氟化物的工艺,确定了氟化的最佳工艺条件,并进行了分析讨论。

The orthogonal design method is used for preparation of rare earth fluoride by rare earth oxide(Gd_2O_3) fluorination with NH_4HF_2 in this paper.The optimum conditions of the reaction is obtained and discussed based on experiments.
