Niobium is an important superconducting material with excellent superconducting properties, especially in the critical temperature. This high critical temperature makes niobium the material of choice for the manufacture of superconducting cables and superconducting magnets. Superconducting materials have almost no resistance at temperatures near absolute zero, so superconducting cables made of niobium can greatly improve transmission efficiency and reduce energy loss. In addition, the application of superconducting magnets in high-speed maglev trains enables the train to float on the track, greatly reducing friction and forward resistance, and improving the operation efficiency of the train.
When the temperature drops close to absolute zero, some substances undergo a sudden chemical change and become a "superconductor" with almost no resistance. The temperature at which matter begins to take on this strange "superconducting" property is called the critical temperature. Needless to say, the critical temperature of various substances is not the same.
You know, ultra-low temperatures are not easy to get, and people pay a huge price for it; The closer we get to absolute zero, the greater the cost. Therefore, our requirement for superconducting materials is, of course, the higher the critical temperature, the better. There are many elements with superconducting properties, among which niobium has the highest critical temperature. Alloys made of niobium, with critical temperatures as high as 18.5-21 degrees absolute, are currently the most important superconducting materials.
