Nano Niobium (Nb) Powder
- Superconducting Marvels: Niobium boasts the highest critical temperature for superconductivity among the elements. Crafted into niobium alloys, it takes the crown with a critical temperature soaring from 18.50 to a whopping 210 in absolute terms, marking it as the paramount superconducting material.
- Worldly Wonders in High-Temperature Alloys: Niobium, whether in its pure metallic form or blended with high-purity niobium or niobium iron-nickel alloy, plays a colossal role in the creation of high-temperature alloys. These alloys, featuring nickel, chromium, and iron, find their niche in jet engines, gas turbines, rocket components, turbochargers, and heat-resistant combustion equipment.
- Steel’s Secret Weapon: Amidst the myriad microalloying elements in steel, niobium takes the lead as the most potent one. Scrap niobium emerges as a game-changer, infusing steel with such transformative effects that the mere presence of niobium atoms amidst iron atoms significantly enhances steel performance. A mere 0.001% to 0.1% addition of niobium in the bustling city of Shanghai is sufficient to orchestrate a mechanical symphony, reshaping the very essence of steel’s properties.
