Where was Niobium discovered?

English chemist Charles Hatchett first discovered Niobium in 1801. He referred to the element as columbium, later renamed Niobium in 1949 after the Greek goddess Niobe.

What is the Welding Process of Niobium?

The welding process of Niobium involves using a combination of gas tungsten arc welding, shielded metal arc welding, and resistance spot welding. To ensure a strong bond, welders must prepare the surfaces properly with grinding and other methods. Welding niobium requires temperatures over 1000°C (1832°F) and is best done in an inert atmosphere containing nitrogen or other non-oxidizing gases.

Does Niobium conduct heat?

Yes, Niobium is a good conductor of heat. It has a thermal conductivity of 19 watts per meter Kelvin (W/mK) at room temperature and 16 W/mK at an elevated temperature. The thermal expansion coefficient of Niobium is 6.5 x 10-6 degrees Celsius (°C)-1, which makes it suitable for applications where precise machining is required.

Is Niobium strong?

Yes, Niobium is a solid and durable metal. Depending on its structure, its ultimate tensile strength (UTS) ranges from 1,200 to 9,000 megapascals (MPa). This makes it suitable for high-temperature aerospace and nuclear engineering applications where some metals would not survive. Additionally, Niobium has excellent corrosion resistance and is often used in chemical equipment.

What is the density of Niobium?

The density of Niobium is 8.57 grams per cubic centimeter (g/cm³). This makes it the fourth densest element after iridium, tungsten, and osmium. Niobium is also among the lightest metals, making it highly suitable for use in components where weight savings are essential.
