Zirconium alloys are currently used in nuclear power plants where they are susceptible to hydrogen pick-up. Hydride precipitation may occur when the hydrogen solubility limit is reached. Various Zr hydride phases, gamma, delta and epsilon have been identified since the 1950s. Combining electron precession microdiffraction, electron energy loss spectroscopy and ab initio electronic calculations, a new Zr hydride named zeta has been identified and characterized. It belongs to the trigonal crystal system with space group P3 m1 and it is fully coherent with the alphaZr matrix.
锆合金目前用于核电站，在那里它们容易吸氢。当达到氢溶解度极限时，可能会发生氢化物沉淀。自20世纪50年代以来，已识别出各种锆氢化物相，即γ相、δ相和ε相。结合电子进动微衍射、电子能量损失谱和从头算电子计算，已识别并表征了一种名为ζ的新型锆氢化物。它属于三方晶系，空间群为P3 m1，与αZr基体完全共格。
