UO2 and uranium hydride (UH3) are formed while heat is evolved, and the metal swells and disintegrates. Introduction An investigation of the uranium-iron phase diagram was undertaken as a preliminary to a study of the ternary system U-Ti-Fe. 2.) Pure uranium is silver in colour and readily oxidises in air. As mentioned earlier, the isotope of uranium U-235 is the ideal fuel for power generation in nuclear power plants.
