Tantalum Capacitor Powder Description

Tantalum capacitor powder is an excellent and low cost alternative to ceramin and aluminum capacitor materials. SSC makes high-quality tantalum powder for capacitors by using sodium reduction processes. Tantalum is twice as dense as steel and is more ductile than steel. It is the fourth-hottest metal and can form very thin and protective oxide layers for high-quality capacitors. Our tantalum capacitor powder is also very easy to handle and flow.

SSC can make materials to your specifications for commercial and research applications.

SSC can make rare metals and other advanced materials into rods, bars, and plates. We can also make other shapes, nanomaterials, and solutions and organometallic compounds.
