Thorium dioxide (ThO2) also called thorium(IV) oxide is a crystalline solid often white or yellow in color. It was formerly known as thoria or thorina. It is produced mainly as a by-product of lanthanide and uranium production.[1]Thorianite is the name of the mineralogical form of thorium dioxide. It is moderately rare and crystallizes in isometric system. The melting point of thorium oxide is 3300 °C – the highest of all known oxides.
