本文研究了铟熔体中磷注入的热力学和动力学。计算了1345~1700K范围内磷气体P(G)、P2(G)和P4(G)与不同浓度In-P熔体的平衡分压。在热力学分析的基础上，详细研究了磷注射合成的动力学过程，包括吸收速率、合成效率、气泡直径、气泡上升距离、鼓泡速率、注射速率、环境压力和熔体浓度之间的关系。计算得到的吸收速率与实验数据吻合较好。在动力学分析的基础上，通过优化合成参数，在3h内合成了20 kg InP多晶。研究发现，在富P熔体凝固过程中，铟和磷在钢锭底部附近发生局部分离。磷沉积呈圆形棒状、柱状多面体、纤维状等放射性特征。分析了分离现象的形成机理。最后提出了获得化学计量比富磷多晶的方法。
In the study, the thermodynamics and kinetics of phosphorus injected into indium melt has been investigated. The partial pressures of the phosphorus gases, P(g), P2(g) and P4(g), in equilibrium with the In-P melt with different concentrations is calculated from 1345 to 1700 K. Based on the thermodynamic analysis, the kinetic process of phosphorus injection synthesis has been studied in details, which involves the relationship among the absorption rate, synthesis efficiency, bubble diameter, rising distance of bubble, bubbling rate, injection rate, environmental pressure and melt concentration. The calculated absorption rate is in good agreement with the experimental data. Based on the kinetic analysis, 20 kg InP polycrystals are synthesized in 3 h by optimizing the synthesis parameters. It is found that local indium and phosphorus separation occurs near the bottom of the ingot during solidification from the P-rich melt. The phosphorus depositions present the radioactivity round rod, columnar polyhedron and fibrous characteristics. The formation mechanism of the separation phenomenon is analyzed. Finally, the methods of obtaining stoichiometric and P-rich polycrystals are put forward.
