Niobium has a melting point of 4474 F, which is 256 degrees lower than that of molybdenum. Pure niobium is very ductile and can be cold worked easily at room temperature. As with tantalum, large reductions are possible between anneals.
The density of niobium is only slightly greater than that of steel and considerably less than that of other refractory metals with higher melting points. Because of this, and the high-temperature strength and favorable nuclear properties, there has been extensive development of niobium base alloys for airborne nuclear reactors.
Introduction As energy demand increases and environmental concern rises, people start to search for new renewable energy sources such as wind, solar, and geothermal power. Lots of advanced techniques including artificial photosynthesis and water-splitting reaction are developed to generate solar fuels. Moreover, photoactive semiconductor materials like Niobium are also utilized to enhance the efficiency of […]
