Ball milling with n2

Dec 29, 2020

May 20, 2021 Impact of Ball Milling on the Structure of Ni/BaH 2. It was shown by the Chen group [] that adding nickel nanoparticles (NPs) to BaH 2 can not only lower the onset temperature in both the nitridation and hydrogenation steps, but also increase the reaction rates in both steps, especially the nitridation step (up to 30 times) relative to the bare BaH 2 in the chemical
