1.引言锇铱合金应用于国防及制革等工业,主要利用其耐磨耐腐蚀性强的优点,国内外多用于常受磨损之部件上。但目前国内使用的金属锇,大部分为进口。因此开展锇金属的回收再生工作,对减少进口具有一定的重要性。锇铱合金废料的提纯方法,经过几年来的生产实践。我们采用了火法结合湿法的分离提纯方法。其原理是利用金属锇易被氧化成四氧化锇而挥发之特性,使与其他金属分
1. Introduction osmium iridium alloy used in defense and tanning industries, the main advantage of its strong wear-resistant corrosion resistance, both at home and abroad often used for wear parts. However, most of the metal osmium used in China is imported. Therefore, to carry out the recovery of osmium metal regeneration work, to reduce the import has a certain importance. Osmium iridium alloy waste purification methods, after several years of production practice. We use the fire method combined with wet separation and purification methods. The principle is the use of metal osmium easily oxidized into osmium tetroxide and volatile characteristics, so that with other metal points
