Irregular Tantalum Powder
Purity: 99% - 99.99%
Particle size: 0.01 - 250 um
Shape: Irregular
Properties: Tantalum metal powder with a dense oxide film that forms on top that exhibits a unidirectional conductive valve metal property. The anode layer has a large dielectric constant of 27.6, a high resistivity of 7.5 x 1010 cm, and a low leakage current in addition to being chemically stable (particularly in acidic electrolytes). Additionally, it benefits from a broad operating temperature range (-80 to 200°C), good dependability, stress resistance, and a lengthy service life. using hydrogen embrittlement and thermal reduction of sodium to produce powder. Alternately, a molten salt electrolyte composed of 55% KCl, 27.5% KF, and 17.5% K2TaF7 is used to create tantalum powder.
It is employed in the production of premium electrolytic capacitors (with a capacity more than five times larger than the ordinary capacity of the same size). It is commonly employed in high-tech industries and military equipment. As an illustration, consider missiles, spacecraft, televisions, electronic computers, etc.Introduction:
Tantalum powder that appears irregular under scanning electron microscopy is known as irregular tantalum powder (SEM). Since there is no form restriction, this tantalum powder can be produced using a variety of methods. As a result, uneven Ta powders are easier to manufacture and have more uses.
Applications:
The capacitor-grade, metallurgical-grade, and medium- and high-voltage tantalum powders are the most frequently seen irregular tantalum powders.
