The production process of powder of niobium metal powder, niobium metallic and capacitor produced using the powder of niobium metal.

摘要

"Production process of powder of niobium metal powder, niobium metallic and capacitor produced using the powder of niobium metal.The invention is m production process of powder of niobium metal characterized by the fact that comprises three stages of reduction of niobium pentoxide, being the first step of reduction by gas reducer of niobium pentoxide and niobium dioxide, the second step of flights were reduced. Niobium monoxide dioxide will for niobium.Through the use of a material collector and a reductive atmosphere of oxygen; the third stage, distinguished by the reduction of niobium monoxide by an alkaline metal or alkaline earth silicate or metal hydride alkaline or alkaline earth silicate in vapor or liquid form.The invention is still a niobium metal powder produced by the process and a capacitor produced by using the powder of niobium metal.
