研究了氢在掺钛FLiNaK熔盐中的溶解度。与熔融盐混合的氢溶性金属粉末可以增加熔融盐的有效氢溶解度，这是目前熔融盐的主要缺点。观察到氢溶解度的显著增加，即使Ti粉末的质量分数仅为0.1重量%。氢溶解度的增加如此之大，以至于钒合金将与Ti粉末/熔融盐混合物相容，这与导致钒合金中不可接受的大氚存量的典型熔融盐不同。此外，钛粉的氧化污染抑制了氢的吸收和释放能力。发现控制熔融盐的纯度是金属粉末混合物概念的关键问题之一。
The hydrogen solubility in a FLiNaK molten salt mixed with Ti powder was investigated. A hydrogen-soluble metal powder mixed with a molten salt can increase the effective hydrogen solubility of the molten salt, which is currently a major disadvantage of molten salts. A significant increase in hydrogen solubility was observed, even with a mass fraction of Ti powder of only 0.1 wt%. The increase of hydrogen solubility was so large that a vanadium alloy would be compatible with the Ti powder/molten salt mixture, unlike typical molten salts that result in an unacceptably large tritium inventory in the vanadium alloy. In addition, contamination of the Ti powder by oxidation suppressed the hydrogen uptake and release capability. Controlling the purity of the molten salt was found to be one of the key issues for the metal powder mixture concept.
