Tantalum Powder

Tantalum Powder

Tantalum powder can be divided into two categories. One is capacitor tantalum, and the other is metallurgical tantalum.

Tantalum Powder Applications

Metallurgical tantalum is used for making tantalum foils and tantalum wires.

Capacitor Grade Tantalum Powder

Purity: Ta >99.95% ~ 99.98% (Metal basis)

Applications:
1. Used to make medium to high voltage (20V-60V) solid tantalum electrolytic capacitors.
