Tantalum | CAS No. 7440-25-7

Q: What is Tantalum (CAS: 7440-25-7)?

Tantalum (CAS: 7440-25-7) is a rare metallic element with the atomic number 73. It is characterized by its high strength, excellent corrosion resistance, and high melting point. Tantalum is a lustrous, silver-gray metal that is dense and has a high atomic number. It is often used in high-temperature applications and in the production of electronic components.

Q: What are the main uses of Tantalum (CAS: 7440-25-7)?

Tantalum (CAS: 7440-25-7) is widely used in various applications, including electronic components such as capacitors, where its high capacitance and stability make it ideal. It is also used in the aerospace industry for its lightweight and high strength properties. In the medical field, tantalum is used in orthopedic implants due to its biocompatibility and ability to withstand high temperatures during sterilization. Tantalum is also used in chemical processing and nuclear industries due to its excellent corrosion resistance.

Q: Is Tantalum (CAS: 7440-25-7) safe?

Tantalum (CAS: 7440-25-7) is generally considered safe for most applications, but precautions should be taken during handling. It is not considered toxic or reactive with human tissue, making it suitable for medical applications. However, it should be stored in a dry environment to prevent corrosion. Direct contact with eyes or skin should be avoided, and appropriate personal protective equipment (PPE) should be used when handling tantalum-containing materials.

Q: How should Tantalum (CAS: 7440-25-7) be stored?

Tantalum (CAS: 7440-25-7) should be stored in a dry environment to prevent corrosion. It is recommended to keep it in a sealed container or in a desiccator to maintain its stability. Tantalum should be stored away from moisture, humidity, and direct sunlight. It is also important to ensure that the storage area is well-ventilated to prevent the accumulation of flammable gases. When handling tantalum, it is advisable to use appropriate safety equipment such as gloves and safety glasses.
