Recently, a new production process of various metals and alloys from their oxides and ores by Cold Hydrogen Plasma (CHP) has been introduced. CHP is produced by using a microwave oven, using less power than the microwave ovens used domestically for cooking food. CHP is very efficient in producing metals and alloys from their oxides because of excited species. These excited species decrease the thermodynamic and kinetic barriers of reduction, making the reduction easier and faster. In the current investigation, nickel has been produced from nickel oxide (NiO) pellets of ~ 2.5 gm to ~ 7.5 gm. The hydrogen flow rate ranges from 70 ml/s to 150 ml/s, and power varies from 600 to 750 W. The time taken for reduction changed between 300 to 1200 s. CHP reduces very fast due to the active oxygen present in it. This faster production of nickel from pellets upto ~ 7.5 gm at such low power opens up the possibilities of upscaling the reduction of NiO by CHP.

最近，一种通过冷氢等离子（CHP）从其氧化物和矿石中生产各种金属和合金的新工艺已被引入。CHP 是通过使用微波炉生产的，比国内用于烹饪食物的微波炉使用更少的功率。由于受激物质，热电联产在从其氧化物生产金属和合金方面非常有效。这些受激物质降低了还原的热力学和动力学障碍，使还原更容易和更快。在目前的调查中，镍是由约 2.5 克至约 7.5 克的氧化镍 (NiO) 颗粒生产的。氢气流速范围为 70 ml/s 至 150 ml/s，功率范围为 600 至 750 W。还原所需的时间在 300 至 1200 s 之间变化。由于其中存在活性氧，CHP 减少得非常快。
