We provide niobium wire mesh, sheet expanded mesh, platinized mesh anode, niobium stamped mesh.
Niobium is not as corrosion resistant as tantalum at high temperatures. Niobium is not attacked by nitric acid up to 100°C, but is strongly attacked by a mixture of nitric acid and hydrofluoric acid. Hot concentrated hydrochloric acid, sulfuric acid, and phosphoric acid will attack niobium, but hot concentrated nitric acid will not attack it. Most acids will not attack niobium at room temperature. It is attacked to some extent by alkaline solutions at all temperatures. Niobium is used in the nuclear industry because of its low capture cross section for thermal neutrons. Niobium can be electrically heated and anodized to a variety of colors, which makes it very attractive in the jewelry industry.
Applications for niobium include sputtering targets, nuclear reactors, natural gas pipelines, jet engines, chemical processing equipment, particle accelerators, turbine blades, automotive parts, capacitors, superconductors, sensitive magnetic imaging equipment, vacuum furnaces, reactor vessels, heat exchangers, sodium lamps, jewelry, steel additives, and optics.
Specifications for our Niobium Mesh
Wire mesh: 20-180 mesh, weaved by niobium metal wire.
Sheet expanded mesh: Opening size 1x1mm to 50 x 50mm, per customer request.
Surface for un-coated Nb mesh: Black oxide, chemically cleaned
Features of platinum-plated niobium mesh:
The anode efficiency is 4-5 times higher than that of platinum-plated titanium mesh, but the cost is 2.5 times lower than that of the latter. Good current distribution and uniform thickness.
The platinum layer is firmly bonded to the niobium-based matrix and the performance is extremely stable. It is used for ceramic composite electroplating and has the advantages of large current and low voltage.
