當時研究鉑的化學家將它置於王水 (氫氯酸和硝酸的混合物)當中,從而產生可溶鹽。製成的溶液每次都留下少量深色的不可溶殘留物。[5]約瑟夫·普魯斯特曾以為這一殘留物是石墨。[5]法國化學家維多·科萊-德科提爾(Victor Collet-Descotils)、福爾克拉伯爵安東萬·弗朗索瓦(Antoine François, comte de Fourcroy)和路易·尼古拉·沃克朗(Louis Nicolas Vauquelin)在1803年也同樣觀察到了這一黑色殘留物,但因量太少而沒有進行進一步實驗。[5]
1813年,英國化學家約翰·喬治·求爾德倫(John George Children)首次熔化銥金屬。[5]1842年,羅伯特·海爾(Robert Hare)首次取得高純度銥金屬。他量得的銥密度為21.8 g/cm3,並發現這一金屬幾乎不可延展,且硬度極高。1860年,亨利·愛丁·聖克萊爾·德維爾和朱爾·亨利·德布雷(Jules Henri Debray)第一次大量熔化銥。每公斤銥的熔化過程需要燃燒超過300升的純O 2和H 2。[5]
銥如此難熔化塑性,這大大限制了它的實際應用。約翰·艾薩克·霍金斯(John Isaac Hawkins)在1834年發明了裝有銥造筆尖的金質鋼筆。1880年,約翰·霍蘭德(John Holland)和威廉·洛弗蘭德·達德利(William Lofland Dudley)利用磷大大簡化了銥的熔化過程,並在美國申請了專利。英國莊信萬豐公司之後表示,他們早在1837年就開始使用類似的方法熔解銥,而且已在多個世界博覽會展出經熔融製成的銥。[5]奧托·佛斯納(Otto Feussner)在1993年第一次在熱電偶中使用銥﹣釕合金材料,使這種新型器材能夠測量高達2000 °C的溫度。[5]
