    Tantalum is twice as dense as steel and it is highly ductile at high temperatures. It has the fourth highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors. Our tungsten powder has high surface area and great handling and flow properties.
    Tantalum powder can be divided into three categories for capacitor tantalum, metallurgical tantalum and Voltage Tantalum Powder.

     

    High-capacitance Tantalum Powder Series

    Features:

    • Produced by the sodium reduction method.

    • It’s suitable for making capacitors with a rated withstand voltage of 4v-40v.

    • Excellent materials for making chips, impregnated tantalum electrolytic capacitors and organic polymer polymer capacitors, which have the advantages of good moldability, high specific capacitance, small leakage current, and low equivalent series resistance.
