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 (-80~200℃), 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 .
Uses: Military equipment and high-tech fields, such as missiles, space vehicles, televisions, electronic computers, etc.
The product has high purity, uniform particle size, complete surface structure, easy dispersion, large specific surface area and high surface activity.
Due to its malleability, high temperature resistance and corrosion resistance, it is widely used in the fields of chemical industry, electronics, military, machinery and aerospace to manufacture electronic components, heat-resistant materials, corrosion-resistant equipment, catalysts, molds, advanced optical glass And so on; medically also used as a human body check-in, surgical material and contrast agent.
