Tantalum Introduction
Tantalum mainly exists in tantalite and accrete to niobium.

Tantalum has very good chemical properties and high corrosion resistance. Experiment proves that at room temperature, tantalum can not react with aqueous alkali, chlorine, bromine water, dilute sulfuric acid and many other medicaments, tantalum only react in hydrofluoric acid and concentrated sulfuric acid.

The characteristics that tantalum have make its application very wide. Tantalum can be used to replace the stainless steel in the equipments for making inorganic acid, which can lengthen the service life of the equipments. In addition, in the chemical industry, electronic and electrical industry, tantalum can replace the precious metal platinum, thus greatly reducing the cost. Tantalum is made into capacitor to be applied in the military equipment. The United States military industry is well developed and the US is the world's largest arms exporter. Half of the world’s tantalum yield is used to produce tantalum capacitors. The United States Defense Logistics Agency is the largest owner of tantalum metal who once bought 1/3 of the world's tantalum powder.
