Niobium Rod

Niobium is a shiny gray metal that shows a blue hue when exposed to gas at room temperature.

The density is 8.57 g/cm3. Niobium is a shiny gray metal, which is paramagnetic and belongs to group 5 on the periodic table. High-purity niobium metal has higher ductility, but it will become harder as the impurity content increases. The arrangement of its outermost electron layer is very different from the rest of the group 5 elements. The same situation also appears in the front and rear ruthenium (44), rhodium (45) and palladium (46) elements.

Because the metal niobium has a high melting point, high strength, and high temperature strength! Excellent properties such as mass ratio, heat resistance, acid and alkali resistance, good thermal conductivity and low neutron absorption cross section are necessary for modern high-tech industries such as fine ceramic composite materials. Less material. As a functional material, niobium is mainly used for superconducting, nuclear power structural materials and super heat-resistant alloys.

High-purity niobium has low high-frequency resistance, which can reduce high-frequency current loss. Although its superconductivity is not as good as that of Nb-Ti alloy and Nb3Sn compound, that is, its superconducting critical temperature Tc is lower, it still has practical applications in the manufacture of superconducting structural materials. High-energy particle accelerator materials have been trial-produced using pure niobium tubes, rods and plates. In addition to researching and reducing high-energy particle acceleration salts and large magnets for particle detection, cold-worked niobium alloy wires, as well as magnet generators, energy storage, power transmission, magnetic levitation trains and nuclear magnetic resonance equipment.

High-purity niobium is used to produce pure niobium products, including niobium powder, niobium ingots, niobium bars, niobium rods and other processed materials of niobium. High-purity niobium alloys and special high-quality niobium alloy steels are used in the fields of aviation, aerospace, energy, electronics, machining industry and environmental protection engineering. The consumption of niobium in this part accounts for about 20% of the total niobium consumption. Crude niobium is used to produce ferro-niobium alloys. , As an additive for refining special steel. In alloy steel, niobium forms NbC and NbN, which can increase the strength of alloy steel. The amount in this aspect is increasing. As an additive in stainless steel and low-alloy high-strength steel, the amount of niobium used is about 75% of the total consumption of niobium, which is the largest consumer market for niobium. Niobium-containing alloy steels are used in the fields of oil and gas, automobiles, construction, chemicals and marine engineering.
