摘要

摘要: 在50～210 GPa的压力范围内，用二级轻气炮和电探针技术对平均密度0＝(6.690.06) g/cm3的三组元Fe/FeO/FeS（质量分数分别为58.96%、35.83%、5.21%）混合物的Hugoniot线进行了实验测量，所得的Hugoniot参数为：C0＝(3.970.07) km/s，＝1.580.03。该混合物Hugoniot线的实测结果与用体积可加性原理计算得到的相同组分混合物的Hugoniot线的符合性很好；根据实验数据还计算了混合物的0 K等温压缩线，发现它与体积可加性原理对单质Fe、FeO和FeS的0 K等温压缩线的计算结果相一致，证明了实验结果的合理性与体积可加性原理的适用性，也表明了此混合物在冲击压缩过程中没有发生过可察觉的化学反应。研究结果亦为今后对外地核各种浓度比Fe-O-S体系候选组分高温高压物态方程及物性的进一步研究奠定了基础。

Abstract: Hugoniot compression curve for the mixture of Fe/FeO/FeS (58.96%/35.83%/5.21%, mass fraction) has been measured from 50 to 210 GPa, using two-stage light-gas gun and electric pin technique. The measured Hugoniot parameters are: C0＝(3.970.07) km/s, ＝1.580.03 and initial density 0＝(6.690.06) g/cm3. Based on additive volume law, the compressional curves of this mixture along Hugoniot and along 0 K isothermal were also calculated respectively according to the Hugoniot curve and 0 K isothermal relevant to the ingredients, which showed both are consistent well with the experimental Hugoniot and the 0 K isothermal deduced from the experimental Hugoniot using the Wu's method. Thus it demonstrated the rationality of this experimental Hugoniot and the applicability of the additive volume law hold for this mixture. For the letter, it also implies that no detectable chemical reactions happen between Fe, FeO, FeS ingredients while they were subjected to shock compression in this work. The above mentioned results provide a basis for investigating the candidate concentrations of Earth's outer core if it is a Fe-O-S assembly, for the further details.
