More about uranium dioxide:
The mineral uraninite naturally contains uranium dioxide, also known as uranium(IV) oxide (UO2), urania, or uranous oxide.
It is a black, radioactive, crystalline powder. It is a component of nuclear reactor fuel rods. MOX fuel is a blend of uranium and plutonium dioxides. It was employed as a black and yellow hue in ceramic glazes and glass before 1960.
The solid is isostructural with fluorite (calcium fluoride), having a cubic configuration with each U being surrounded by eight O nearest neighbours. When uranium dioxide comes into contact with carbon, it carbonises and produces carbon monoxide and uranium carbide.
