作者在辉锑锡铅矿-硫锑锡铁铅矿-potosiite以及圆柱锡矿两个固溶体系列的实验研究基础上,合成出铅全部被二价锡取代生成的无铅端员——无铅辉锑锡铅矿和无铅圆柱锡矿。并进一步在Fe-Sn-Sb-S体系内确定了第三个相——含铁、锑的斜方硫锡矿固溶体相的存在。无铅辉锑锡铅矿和无铅圆柱锡矿作为纯相只能在高温下被合成。铁锑斜方硫锡矿虽然也可以在600℃被合成,但在500℃以下,它在更广泛的范围内存在。文章也涉及到无铅的SnS-SnS_2-FeSb_2S_4假三元系内相的关系,即600℃时所观察到的随四价锡增加而依次出现的相及相的共生。
Based on the experimental study of two solid solutions series of antimony tin-lead-sulfur-antimony tin iron-lead-potosiite and cylindrical tin mine, the lead-free end-member with all the lead substituted by bivalent tin was synthesized. Antimony tin lead and lead-free cylindrical tin. Furthermore, the existence of the third phase, an iron and antimony orthorhombic solid solution phase, was determined in the Fe-Sn-Sb-S system. Lead-free bismuth antimony tin lead and lead-free cylindrical tin as a pure phase can only be synthesized at high temperatures. Although it can be synthesized at 600 ℃, it is found in a wider range below 500 ℃. The article also deals with the relationship between the internal phases of the unleaded SnS-SnS_2-FeSb_2S_4 pseudo-ternary system, ie the phase and phase symbiosis observed at 600 ° C with the increase of tetravalent tin.
