Tantalum Powder

Tantalum in powder form, dark gray or silver gray, is an important raw material for the preparation of capacitors and tantalum materials.

Classification Tantalum powder is usually divided into two categories according to its use: capacitor grade and metallurgical grade. Capacitor grade tantalum powder is generally divided into three series: low voltage series (operating voltage not more than 25V), medium voltage series (operating voltage of 32 ~ 40V) and high voltage series (operating voltage not less than 50V).

Production Process of Tantalum Powder

Production Process of Tantalum Powder

The methods of preparing tantalum powder include metal thermal reduction of tantalum pentoxide, carbon reduction, molten salt electrolysis, hydrogen reduction of tantalum halide, metal thermal reduction and metal thermal reduction of tantalum containing fluoride complex. At present, tantalum powder is mainly prepared by sodium reduction of potassium flutantalate.
