Niobium powder
Niobium is a silver-gray, soft, and ductile transition metal with a melting point of 2468°C, a boiling point of 4742°C, and a density of 8.57 g/cm3. Niobium is stable in the air at room temperature, and is not completely oxidized when it is red hot in oxygen. It can directly combine with sulfur, nitrogen, and carbon at high temperatures, and can form alloys with titanium, zirconium, hafnium, and tungsten. It does not interact with mineral acids or alkalis, nor is it soluble in aqua regia, but it is soluble in hydrofluoric acid. Because the physical and chemical properties of niobium are similar to those of tantalum, and the two elements are often co-existing, it is difficult to separate pure niobium without impurity tantalum.

Product description

Niobium is a silver-gray, soft, and ductile transition metal with a melting point of 2468°C, a boiling point of 4742°C, and a density of 8.57 g/cm3.

It can directly combine with sulfur, nitrogen, and carbon at high temperatures, and can form alloys with titanium, zirconium, hafnium, and tungsten. It does not interact with mineral acids or alkalis, nor is it soluble in aqua regia, but it is soluble in hydrofluoric acid. Because the physical and chemical properties of niobium are similar to those of tantalum, and the two elements are often co-existing, it is difficult to separate pure niobium without impurity tantalum.

Uses: for processing raw materials and production of welding electrodes and refractory materials; pure niobium is used to remove residual gas in electron tubes; adding niobium to steel can improve the oxidation resistance of steel at high temperatures and improve the welding performance of steel; niobium is also used Manufacturing high temperature metal ceramics.

Niobium target
Niobium is a kind of refractory rare metal with a steel-gray luster. Its melting point is 2467℃ and its density is 8.6g/cm3. Niobium has good low-temperature plasticity and can be cold-pressed into rods, sheets, wires and other products. Niobium can withstand high temperature and high strength, and still has sufficient strength, plasticity and thermal conductivity above 1000°C. Superconductivity is best at extremely low temperatures. For example, its resistance is close to zero at minus 260°C. It is currently the most important superconducting material.
