超声波技术在贵金属冶金及材料制备中的应用

摘要

Application and research progress of ultrasonic technology in the leaching of precious metals and material preparation were reviewed. Ultrasonic waves generate strong impact which could increase the leaching speed, improve the leaching efficiency and strengthen the leaching of precious metals. During the process of material preparation, the micro jet of ultrasonic waves would reduce the particle size of precious metal powders and distribute them equally. And ultrasonic could improve the electrode performance when applied to prepare the platinum electrode.%综述了近年来超声波技术在贵金属的提取冶金及材料制备方面的应用和研究进展.超声波在界面上产生强烈的冲击和空化作用可加快浸出速度,提高浸出效率,强化浸出贵金属;在材料制备过程中,超声波产生的微射流可使生成的贵金属粉粒径减小、分布均匀,应用于制备铂电极中可提高电极性能.
