在净化氩气气氛保护下,用片状ZrO_2(2.4％MgO稳定)固体电解质所组成的氧浓差电池,测定了1600℃铁液中Si-O平衡时的氧活度。由此进一步求算出熔体的其他有关热力学参数,其结果为,并将其与文献中的数据作了对比和讨论。
Under the protection of argon gas atmosphere, the oxygen activity of the Si-O balance in the liquid iron of 1600 ℃ was measured by oxygen concentration cell consisting of sheet-like ZrO_2 (2.4% MgO stabilized) solid electrolyte. Further calculation of the other thermodynamic parameters of the melt results in a comparison and discussion with the data in the literature.
