摘　　要： 通过对硫镓银多晶合成实验过程中容器易发生爆炸的原因进行分析研究,提出了两温区气相输运、温度振荡合成AgGaS_2多晶的新方法,即通过分段升温同时旋转合成炉逐步消耗参与反应的硫,然后在高温进行两温区气相输运反应后再进行温度振荡混合反应,减小反应过程中合成管内压力,避免了容器爆炸的发生,获得了高纯单相的AgGaS_2多晶原料。 This paper presented a new procedure of AgGaS_2 polycrystalline synthesis via analyzing and exploring the reasons of explosion during the synthetic processes in the vessel chamber. The new procedure includes those steps such as two-temperature-zone vapor transportation and temperture oscillation. The new method synthesized high purified and polycrystalline AgGaS_2 with Single phase. Explosion was successfully avoided due to the reduction of pressure in the synthetic chamber. Single crystal AgGaS_2 was obtained with a size of φ10×15mm by Bridgman's method using the synthetic AgGaS_2. XRD was used to characterize those synthetic materials and the results proved that synthetic AgGaS_2 was polycrystalline with single phase.
