Product Name: Tantalum powder
Specification: Various specifications and sizes can be processed and customized according to customer requirements
Physical and chemical properties:
The dense oxide film formed on the surface of tantalum powder has the property of unidirectional conductivity. The anode film has stable chemical properties (especially in acidic electrolyte) and high resistivity (7.5%) × 1010 Ω· cm), high dielectric constant (27.6) and low leakage current. It also has the advantages of wide working temperature range (- 80 ~ 200 ℃), high reliability, earthquake resistance and long service life. Sodium thermal reduction and hydrogen embrittlement were used to prepare powder. Or use 55% kcl-27.5% kf-17.5% K2TaF7 as molten salt electrolyte to produce tantalum powder. It is used to manufacture high-quality electrolytic capacitors (the capacitance is more than 5 times larger than the ordinary electric capacity of the same size). It is widely used in military equipment and high-tech fields. Such as missiles, space vehicles, televisions, electronic computers, etc.
1. Capacitor tantalum powder and its application tantalum electrolytic capacitor is an electronic device that takes tantalum as a metal anode and directly generates a dielectric (insulated in the direction of electric field and conductive when reverse voltage is applied) oxide film on the surface of tantalum through anodic oxidation.
2. Tantalum and its alloys and applications the tolerance of tantalum to interstitial elements and reasonable elastic modulus make it very attractive as the matrix element of the alloy
