Ferrouranium : ウィキペディア英語版 | Ferrouranium Ferrouranium, also called ferro-uranium, is a ferroalloy, an alloy of iron and uranium, after WWII usually depleted uranium. ==Composition and properties== The alloy contains about 35–50% uranium and 1.5–4.0% carbon. At least two intermetallic compounds of iron and uranium were identified: U6Fe and UFe2. Small amounts of uranium can drastically lower melting point of iron and vice versa. reportedly melts at 1230 °C, at 805 °C; a mixture of these two can have melting point as low as 725 °C, a mixture of iron and can have melting point of 1055 °C.〔(【引用サイトリンク】title=Corrosion-resistant Fe-Cr-uranium238 pellet and method for making the same - US Patent 4383853 Description )〕 As ferrouranium readily dissolves in mineral acids, its chemical analysis is not problematic.
