Note: We can supply different size products of ultrafine metal tantalum according to client's requirements.
The product has high purity, uniform particle size, complete surface structure, easy dispersion, large specific surface area and high surface activity.
Application of ultrafine metal tantalum:
Metal ruthenium powder, a dense oxide film formed on the surface has a unidirectional conductive valve metal property. The prepared anodic film has stable chemical properties (especially stable in an acidic electrolyte), high resistivity (7.5×10 10 Ω·cm), large dielectric constant (27.6), and small leakage current. It also has a wide operating temperature range (-80 ~ 200 ° C), high reliability, shock resistance and long service life. It is made by sodium heat reduction and hydrogen embrittlement. Or the molten salt electrolyte is composed of 55% KCl-27.5% KF-17.5% K2TaF7 to produce tantalum powder. Used to manufacture high quality electrolytic capacitors (capacitance is more than 5 times larger than ordinary capacity of the same size). Widely used in military equipment and high technology fields. For example, space vehicles, televisions, electronic computers, etc.
SEM & XRD of ultrafine metal tantalum:
Storage conditions:
ultrafine metal tantalum should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
