Description

Thorium CAS NO 7440-29-1 is a naturally occurring, slightly radioactive, silvery-white actinide metal. It is valued in advanced industrial and energy applications for its unique nuclear properties and high-temperature stability. This material is essential for manufacturers and research institutions in the nuclear energy, aerospace, and high-performance alloy sectors. Its primary commercial significance lies in its use as a fertile material for nuclear fuel and in high-strength, heat-resistant metal alloys.

Application

• Nuclear Fuel Cycle: Used as a fertile material (Th-232) in nuclear reactors, which can be converted to fissile uranium-233.
• High-Temperature Alloys: An additive in magnesium and other non-ferrous alloys to enhance strength and creep resistance at elevated temperatures.
• Aerospace Components: Employed in coatings for tungsten wire used in electronic devices and in high-temperature structural parts.
• Gas Mantles: Historical and specialized use in producing incandescent mantles for portable gas lighting.
• Catalyst: Serves as a catalyst in certain petrochemical and organic synthesis reactions.
• Research & Development: A key material in scientific research for nuclear physics, material science, and radiation studies.
• Electronics: Used in the production of photoelectric cells and sensors.
• Welding Electrodes: A component in thoriated tungsten electrodes for arc welding and cutting.

Quality Control

Our thorium metal is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and traceability. Quality assurance includes verification of isotopic composition, radiological purity, and metallic impurity profiles. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications for purity, isotopic abundance (Th-232), and key elemental impurities. We adhere to relevant nuclear material accounting and safety standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric nature in powder form and the property of being easily oxidized (store under inert atmosphere), it must be stored under an inert gas (argon or nitrogen) in a cool, dry, and well-ventilated area dedicated for radioactive materials. Keep away from strong acids, oxidizing agents, and moisture. Comply with all local, national, and international regulations for the storage of radioactive substances.
