ASTM B392 Niobium Metal Niobium Plate Excellent Acid Resistance
Manufacturers wholesale various sizes high-purity niobium plate and niobium alloy plate
Product Description
At room temperature, niobium does not react with air and is not completely oxidized when red hot in oxygen. Niobium can be directly chemically combined with sulfur, nitrogen and carbon at high temperatures. Niobium does not react with inorganic acids or bases and is insoluble in aqua regia, but is soluble in hydrofluoric acid. Niobium is present in the earth's crust at a level of 20 ppm and the distribution of niobium resources is relatively concentrated. Due to its good superconductivity, high melting point, corrosion resistance and wear resistance, niobium is widely used in steel, superconducting materials, aerospace, atomic energy and other fields.
