Tantalum is a dense, grayish-blue metallic chemical element that has the symbol Ta and atomic number 73. It is highly resistant to corrosion and has a high melting point. Tantalum is a rare metal that is found in minerals such as tantalite and columbite. It is used in a variety of applications, including electronic devices, capacitors, and surgical implants. Tantalum is often used as a substitute for platinum in certain applications because it is less expensive and has similar properties. The production of tantalum is concentrated in a few countries, such as Brazil, Canada, and Australia. Due to its scarcity, tantalum is classified as a critical raw material by many governments and organizations.
