平衡和高温x射线研究表明，氢在铌中的固溶体在整个系统中产生。在低温和低压条件下存在混相间隙，其临界点为140~ 0.01 mm汞氢压力和0.3 H/Nb。300~ 176的吸附速率最初呈线性。在较高温度下，吸附速率由金属基体中的扩散控制。600~ 176处的扩散系数可表示为：
Equilibria and elevated-temperature x-ray studies show that a solid solution of hydrogen in niobium is produced throughout most of the system. A miscibility gap was found at low temperatures and pressures with a critical point at about 140~ 0.01 mm of mercury hydrogen pressure, and 0.3 H/Nb. Sorption rates at 300~ 176 were initially linear. At higher temperatures, sorption rates were controlled by diffusion in the metal matrix. Diffusion coefficients at 600~ 176 can be expressed by:
