Capacitor Grade Tantalum Wire Chemical Properties

Capacitor Grade Tantalum Wire Chemical Properties

Antioxidant properties: It is very stable in the air at room temperature, but its antioxidant properties are very poor at high temperatures.

It will oxidize when heated to above 300°. As the temperature increases, the oxidation becomes more severe.

Corrosion resistance: Tantalum has good corrosion resistance in most acids.

At a temperature of 150°, hydrochloric acid, nitric acid, phosphoric acid and organic acids of any concentration cannot corrode tantalum; but tantalum can be dissolved in hydrofluoric acid, a mixture of hydrofluoric acid and nitric acid; in a mixture of hydrofluoric acid and hydrochloric acid Dissolution is more intense in medium.
