氟钽酸钾钠还原工艺中注钠计量控制方法的研究

Research on Na Solution Dosing Methods during Na Reduction of K_2TaF_7

对金属钠溶液的多种计量控制方法进行了分析研究，结果表明：采用电阻法来控制注销量及注钠速度，方法不仅经济、实用，而且灵敏度高。该法不仅可以解决国内一些钽粉生产厂家因注销计量控制不灵敏而引起的袒粉质量问题，而且还可以用于其他导电液的计量控制。

Research was made on Na solution dosing methods during Na reduction of K2TaF7. Results show that the resistence method is practical with high sensitivity, resulting in increase of quality of Ta powder and the method also useful for dosing of other electroconductive solution.
