摘要
用输运法测定了2zns (s)+ 2zn (g)+ S2(g)(1)、ZnS(s)+ Si(s) + Zn(g)+ SiS(g)(2)在1000℃左右反应的平衡常数和标准自由能变化。得到了以下自由能ΔG°= 178 900-92.4 T cal mol-1 1293 K (1b)， ΔG°= 101 700-65.7 T cal mol-1 1293 K (2b)，结合其他研究者的结果，得到了反应(3)的自由能变化:2Si(s)+ S2(g)= 2 SiS(g)(3)， ΔG°= 24 500-39.0 T cal mol-1结合其他研究者的结果，估计了SiS2的形成自由能(s, l, g)。
Thermodynamics of silicon sulphides and zinc sulphide
The equilibrium constant and standard free energy change for the reactions: 2 ZnS(s)⇌2 Zn(g)+ S2(g)(1), ZnS(s)+ Si(s)⇌Zn(g)+ SiS(g)(2) have been measured around 1000°C by a transportation method. The following free energies were obtained ΔG°= 178 900–92.4 T cal mol–1 1293 K (1b), ΔG°= 101 700–65.7 T cal mol–1 1293 K. (2b) By combination, the free energy change for reaction (3) is obtained: 2Si(s)+ S2(g)= 2 SiS(g)(3), ΔG°= 24 500–39.0 T cal mol–1 Combined with results of other investigators the free energy of formation of SiS2(s, l, g) is estimated.
