Material Description

Niobium is a grey-white metal with mel間員ting point of 2468℃, boili相女ng point of 4,742 ℃, and density of 師和8.57g/cm3. Niobium is stable in air司城 at room temperature, and cannot be 秒房fully oxidized in oxygen even when it’s店視 hot and turns red; it ca銀劇n directly compound 間腦with sulfur, nitrogen數暗, and carbon at high temperature,子上 can form alloys with titani小司um, zirconium, hafnium, and車街 tungsten. It has no chem城資ical action with inorganic aci劇劇ds or alkali; it is not dissolved in a子窗qua regia, but can be dissolved i現對n hydrofluoric acid. Niobium 到草has oxidation states of -1, + 2, + 3, +聽開4 and +5, in which +5 c低愛ompound is most stable.

Areas of Application

Because of high melting point, corros年銀ion-resistance, cold-proce視書ssing performance and 開朋other characteristics, niobium 學河and niobium alloy bar and wire product水紅s are widely used in chemical愛音, electronics, aviation and space輛如 fields. With a densit煙相y of 16.57g/cm3, niobi錢錢um and niobium alloy bars are used as 機煙structural materials 匠靜for aero-engines and rocket nozzl厭在es, internal components and co聽理ating materials for reactors, and費中 various corrosion-resistant parts 玩睡for corrosion environme制間nt with nitric acid, hydrochlor醫校ic acid or sulfuric acid. Adding zi術著rconium into niobium can significant國他ly improve the antioxidant properties 下從and strength of materials; by this way小吃, niobium and niobium zir木明conium alloy wires ar務行e widely used in production of h吧花igh pressure sodium lamps and a白好node lead wires for electro是得lytic capacitor.
