Description: Metal tantalum powder, the dense oxide film formed on the surface of the powder has the properties of one-way conductive valve metal. The prepared anode film has stable chemical properties (especially stable in acid electrolyte), high resistivity (7.5×1010Ω·cm), high dielectric constant (27.6), and low leakage current. It also has the advantages of wide operating temperature range (-80~200ºC), high reliability, shock resistance and long service life. Adopt sodium heat reduction and hydrogen embrittlement method to make powder. Or use 55%KCl-27.5%KF-17.5%K2TaF7 to form molten salt electrolyte to produce tantalum powder. Used to manufacture high-quality electrolytic capacitors (the capacitance is more than 5 times larger than the ordinary capacitance of the same size).
Uses: Military equipment and high-tech fields, such as missiles, space vehicles, televisions, electronic computers, etc.
