Using high-tellurium copper crude selenium as raw material, the process of preparing 4N selenium powder by high temperature oxidatio—water dissolution-low temperature reduction—temperature rise transformation was studied. The effects of key process parameters in each process on the purification of crude selenium to prepare 4N selenium powder were investigated, and the reduction reaction of selenium and the competitive behavior of selenium and tellurium were analyzed based on thermodynamic theory. The results show that under the optimal process conditions of oxidation temperature of 550 ℃, oxidation time of 3.0 h, oxygen flow rate of 2.5 m3/h, reduction temperature of 25 ℃, hydrazine hydrate concentration of 15%, stirring speed of 300 r/min, reaction endpoint solution pH=6.5, and transformation temperature of 55 ℃, the selenium product can meet the standard of 4N selenium powder. The method can provide a new technical route for the production of high-purity 4N grade selenium.

以高碲铜粗硒为原料,研究了采用高温氧化—水溶-低温还原—升温转型工艺制备4N硒粉,考察了各工序关键工艺参数对粗硒提纯制备4N硒粉的影响,并根据热力学理论分析了硒的还原反应及硒碲的竞争行为。结果表明:在氧化温度550 ℃、氧化时间3.0 h、氧气流量2.5 m3/h、还原温度25 ℃、还原剂水合肼浓度15%、搅拌速度300 r/min、反应终点溶液pH=6.5、转型温度55 ℃最优工艺条件下制备的硒产品能达到4N硒粉标准。该法可为生产高纯度4N级硒提供一种新技术路径。

以高碲铜粗硒为原料,研究了采用高温氧化—水溶-低温还原—升温转型工艺制备4N硒粉,考察了各工序关键工艺参数对粗硒提纯制备4N硒粉的影响,并根据热力学理论分析了硒的还原反应及硒碲的竞争行为。结果表明:在氧化温度550 ℃、氧化时间3.0 h、氧气流量2.5 m3/h、还原温度25 ℃、还原剂水合肼浓度15%、搅拌速度300 r/min、反应终点溶液pH=6.5、转型温度55 ℃最优工艺条件下制备的硒产品能达到4N硒粉标准。该法可为生产高纯度4N级硒提供一种新技术路径。

Using high-tellurium copper crude selenium as raw material, the process of preparing 4N selenium powder by high temperature oxidatio—water dissolution-low temperature reduction—temperature rise transformation was studied. The effects of key process parameters in each process on the purification of crude selenium to prepare 4N selenium powder were investigated, and the reduction reaction of selenium and the competitive behavior of selenium and tellurium were analyzed based on thermodynamic theory. The results show that under the optimal process conditions of oxidation temperature of 550 ℃, oxidation time of 3.0 h, oxygen flow rate of 2.5 m3/h, reduction temperature of 25 ℃, hydrazine hydrate concentration of 15%, stirring speed of 300 r/min, reaction endpoint solution pH=6.5, and transformation temperature of 55 ℃, the selenium product can meet the standard of 4N selenium powder. The method can provide a new technical route for the production of high-purity 4N grade selenium.
