摘要
简要介绍了氮化锰生产的理论依据及工业生产氮化锰的工艺流程。采用热重分析方法研究了氮化锰产品在氩气下的热稳定性。研究结果表明:当温度升至800℃以上时,氮化锰会发生热分解,氮化温度对氮化锰产品的质量有重要影响;对氮化锰球产品的氮质量分数进行了检测分析,初步实验研究表明:产品氮质量分数低、成分偏差较大的原因是在氮化过程中氮化温度制度不合理以及锰氮反应放热引起了金属锰熔化。同时探讨了关于氮化锰球生产工艺优化的技术思路。
It briefly introduces the principle of manganese nitride production and its industrial process flow, studies the thermostability of manganese nitride products under argon atmosphere by means of thermal gravimetric analysis. The result shows that manganese nitride products would occur decomposition when the temperature rises to 800 ~C or above. Therefore, the temperature has an important influence on the quality of manganese nitride products. After detection analysis on nitrogen content of manganese nitride pellets, the preliminary research explains that products with low nitrogen content and large composition deviation attribute to unreasonable nitration temperature regime and metallic manganese melting caused by manganese-nitrogen reaction heat release. In addition, it discusses production technology optimization on manganese nitride pellets.
