熔盐电解精炼铪

Molten Salt Electrorefining of Hafnium

用含铪50％左右的熔炼喷溅物制铪氟酸钾电解质,对废铪料进行电解精炼。介绍了半封闭、半连续生产的电解槽。获得的铪粉经电子束提纯,可得符合原子能级标准的铪锭。

The waste Hf are electrorefined and the K_2HfF_ electrolyte are made from spraying materials containing 50% Hf. Hf powder so obtained are smelted by electron-beam into ingot which accords with the standard of atomic energy level. This paper also describes electrolyser with semi-closed and semi-continuous operating.
