What is the role of tantalum niobium?

Niobium is a rare metal and has important applications in the field of material science and engineering in the 21st century. Tantalum-niobium ore is a general term for ores containing tantalum and niobium, and is the main mineral source for extracting tantalum-niobium metal. what is the specific role of tantalum niobium?

The preparation of metal tantalum

The preparation of metal tantalum

The preparation of metallic tantalum is a process in which a pure tantalum compound is reduced to metallic tantalum by a reducing agent. The raw materials of the pure tantalum compound used are tantalum pentoxide, tantalum pentachloride, tantalum pentafluoride and fluorine salts (e. g., K2TaF7). The reducing agent has sodium, magnesium and other active metals and carbon and hydrogen. The melting point of tantalum is as high as 3669K, so the powder or sponge metal is obtained after reduction. Further smelting or refining is required to obtain dense metal.

Tantalum smelting steps

Tantalum smelting steps

Tantalum niobium ore is the main raw material for the production of tantalum, but tantalum niobium ore is often accompanied by a variety of metals, so the main step of tantalum smelting is to decompose the concentrate, purify and separate tantalum and niobium to produce pure compounds of tantalum and niobium, and finally to produce metal.

Application of Tantalum in Military Industry and Aerospace

Application of Tantalum in Military Industry and Aerospace

Many key components in the aerospace and military industries work under high temperature conditions and are subject to the interaction of thermal, mechanical and chemical processes, which lead to serious ablation and wear. Therefore, materials with good wear and ablation resistance at high temperatures are urgently needed in the cutting-edge industrial field.
