Our production process


In our chemical plant, tantalum and niobium undergo a series of process steps including separation, purification using dissolution and extraction techniques followed by crystallization processes. As a result of these processes, two important compounds are produced: Potassium Fluotantalate (K2TaF7) and Niobium Pentoxide (Nb2O5). Through subsequent metallurgical processes, Fluotantalate (K2TaF7) is further transformed into Tantalum Metal Powder and Tantalum Capacitor Powder, which find application in various industries. Niobium Pentoxide finds application in the optical industry.


At our metal plants, we produce powders applying several process steps such as high-temperature reactions, multiple heat treatments, milling & screening, sieving, and granulation to manipulate the composition and physical properties of powder particles. These techniques enable us to finely tune the particles to meet the specific requirements of our customers, including desired chemical composition, as well as physical and electrical properties of our tantalum capacitor powders. They play a crucial role in supporting the growth of the electronics industry.
