我们提出的研究富硅部分的Fe - Si系统进行了Mössbauer光谱相动力学。在非常纯的样品中获得标准光谱，这些光谱应用于商业75&硅铁的研究。我们发现半稳定的高温α相，以空位的大量集中而著称，需要多个四极偶极来拟合数据。最后说明了Mössbauer效应如何应用于硅铁生产的质量控制。
We present studies of phase dynamics of the silicon rich part of the Fe−Si system performed with Mössbauer spectroscopy. Standard spectra are obtained in very pure samples and these are applied to the studies of commercial 75& ferrosilicon. We find that the semistable high temperature alpha phase, known for considerable concentration of vacancies, needs multiple quadrupole doublets to fit the data. Finally it is shown how the Mössbauer effect can be applied to quality control in ferrosilicon production.
