Silicon Carbide – SiC Silicon carbide was discovered in 1893 as an industrial abrasive for grinding wheels and automotive brakes. About midway through the 20 th century, SiC wafer uses grew to include in LED technology. Since then, it has expanded into numerous
Relative Permittivity - the Dielectric Constant
The dielectric constant - also called the relative permittivity indies how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the permittivity of space or vacuum".

Silicon Carbide - MSEE-P A Team Project
Silicon carbide (SiC) has been given a renewed attention as a potential material for high-power and high frequency appliions requiring high-temperature operation. Some of the possible appliions of SiC as a material for power electronics are for advanced turbine engines, propulsion systems, automotive and aero- space electronics, and appliions requiring large radiation-damage resistance.
Hamaker constants of inorganic materials
126 L. BergstrSm /Adv. Colloid Interface Sci. 70 (1997) 125-169 methods generally yield non-retarded Hamaker constants which do not differ signifi- cantly. This is not true for all materials, e.g. water, where a more detailed representation using

Dielectric Constant Values - Clipper Controls
Dielectric Constant (k) is a nuer relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current. The capacitance created by the presence of the material is directly related to the Dielectric Constant of the material.
Electrical Properties of Boron Nitride Matrix Composites: …
SiC has a higher dielectric constant than that of BN. The microstructure of these composites is anisotropic, with BN platelets preferentially oriented perpendicular to the hot‐pressing direction. Samples measured in this direction exhibit a lower dielectric constant than those measured parallel to the hot‐pressing direction.
