What is Thorium?

Thorium is a weakly radioactive actinide metal. It is about three times more abundant than uranium in Earth crust and is considered a potential future nuclear fuel in thorium reactors due to its favourable nuclear properties.

Formula & Notation

Th

Properties & Characteristics

Appearance: silvery metal, tarnishes to grey. Melting point: 1750 °C. Boiling point: 4788 °C. Density: 11.7 g/cm³.

Uses & Applications

Potential nuclear fuel in thorium-cycle reactors. Formerly used in gas mantles (thoriated mantles). Used in high-temperature ceramics and as alloying agent in magnesium alloys.

Safety Information

Radioactive; alpha emitter. Dust inhalation risk. Regulated as radioactive material. Long half-life (14.05 billion years) means it accumulates in the environment.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
