在所评估的Si-Zr相图（图I）中的平衡相是：（Si）; Si 2 Zr;~-和aSiZr; f~-和aSi 4 Zr; Si 2 Zr 3; Si 3 Zr 5; SiZr 2; SiZr 3;（~ Zr）;和（aZr）。图1的特殊点总结在表1中。许多研究一致认为，有几个金属间化合物相的Si-Zr系统，但缺乏适当的化学计量的准确性。不一致的原因之一是少量的杂质使Si 3 Zr 5稳定，使其他相相对不稳定。评估图主要基于[76 Koc]。[10 Bar]和[68 Bru]和[76 Alc]以及[汉森]、[Elliott]和[Shunk]对该系统进行了审查。
The equilibrium phases in the assessed Si-Zr phase diagram (Fig. I) are:(Si); Si2Zr;~-and aSiZr; f~-and aSi4Zrs; Si2Zr3; Si3Zr5; SiZr2; SiZr3;(~ Zr); and (aZr). Special points of Fig. 1 are summarized in Table 1. Many investigations concur that there are several intermetallic phases in the Si-Zr system, but unanimity as to the appropriate stoichiometries is lacking. One of the reasons for disagreement is that a small amount of impurity stabilizes Si3Zr5 and makes other phases relatively unstable. The assessed diagram is based primarily on [76Koc]. This system was reviewed by [10Bar] and more recently by [68Bru] and [76Alc], as well as [Hansen],[Elliott], and [Shunk].
