摘要
以金属镁和升华硫为原料,采用双温区反应炉合成了MgS,合成的MgS产量高且工艺安全。利用X射线衍射分析了合成产物的相组成,考察了合成温度(θh和θl)对合成体系和相组成的影响。研究了合成体系内升华硫的蒸发量与合成体系容积大小、合成温度以及合成体系抗压强度等参数间的关系。结果表明:合成体系内的最大升华硫蒸发量应小于2.45g,θh和θl明显影响合成产物的相组成,随着θh和θl和保温时间的提高,MgS衍射峰强度逐渐增大,反应进行得更加充分。反应的最佳工艺参数:θh为1000℃,θl为100℃,保温时间为32h。
A large amount of magnesium sulfide was synthesized safely with a two-zone furnace method by using magnesium metal and sublimed sulfur as raw materials.The phase composition of the products was identified by X-ray diffraction.The influences of the synthesis temperature(θh and θl) on the synthesis system and the phase composition were investigated.The relationships among the maximum amount of gaseous sulfur,the volume of the quartz tube,the synthesis temperature and the pressure in the quartz tube were studi...
