It primarily consists of thorium dioxide (ThO2) but may contain other elements like uranium, rare earth elements, and tin. Crystallizing in the tetragonal system, it forms prismatic or tabular crystals but is more commonly found in massive or granular forms. Thorite is an important source of thorium, a valuable radioactive element.

What is thorium? Thorium is a naturally occurring radioactive metal that is found in soil, rock, and water. It is formed by the radioactive decay of uranium. Minerals such as monazite, thorite, and thorianite are rich in thorium and may be mined for the metal. Thorium has coloring properties that have made it useful in ceramic glazes.
