Research on Fluorine Content Control in Ta_2O_5 and Nb_2O_5 AITranslate
Abstract AITranslate
Ta2O5 and Nb2 O5 powders are prepared with tantalum solution and niobium solution as the raw material and by ammonia neutralization precipitation-washing-drying-calcination. Influences of wash water amount and calcining time on fluorine content of the product were studied. The results show that fluorine content in tantalum and niobium oxides increases after they are placed in hydrofluoric acid atmosphere for some time,and therefore their fluorine content can be controlled at 0.07% -0.12 %, meeting the application requirements of foreign fiber field for tantalum and niobium oxides.
