Tantalum is a chemical ... The differences between tantalum and niobium were demonstrated unequivocally in 1864 ... is a hard ceramic that is used in cutting tools ...
A ceramic capacitor is a non-polarized fixed capacitor made out of two or more alternating layers of ceramic and metal in which the ceramic material acts as the dielectric and the metal acts as the electrodes.
The main difference between the polymer capacitors is the anode material and its oxide used as the dielectric: Polymer tantalum electrolytic capacitors use high purity sintered tantalum powder as an anode with tantalum pentoxide (Ta 2 O 5 ) as a dielectric and
A typical ceramic through-hole capacitor. A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.
Tantalum capacitors in different styles: axial, radial and SMD-chip versions (size comparison with a match) 10 μF 30 VDC-rated tantalum capacitors, solid electrolyte epoxy-dipped style. A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits.
Solid tantalum electrolytic capacitors with manganese dioxide electrolyte or polymer electrolyte are damaged by peak or pulse currents. [51] [52] Solid Tantalum capacitors which are exposed to surge, peak or pulse currents, for example, in highly inductive circuits, should be used with a voltage derating. If possible, the voltage profile should ...
In 1809, English chemist William Hyde Wollaston compared the oxides derived from both columbium—columbite, with a density 5.918 g/cm 3, and tantalum—tantalite, with a density over 8 g/cm 3, and concluded that the two oxides, despite the significant difference in density, were identical; thus he kept the name tantalum.

Ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand the chemical erosion that occurs in other materials subjected to acidic or caustic ...
