Niobium Mesh Description
Niobium doesn't react with inorganic acid or alkali, nor does it dissolve in water. Niobium is soluble in hydrofluoric acid. Niobium has a better acid resistance than zirconium, but it is less resistant than tantalum.
Niobium wire mesh, sheet expanded mesh, and niobium stamped mesh are our mesh types.
Niobium meshes can be used as screens, gauze, or platinized mesh anodes.
