Beryllium oxide, aluminum nitride, alumina, silicon carbide, and silicon ni-tride have a permittivity higher than thoses of most organic materials [16,17]. Silicon carbide is a semiconductor and is often coined with BeO to obtain a low-loss sub-strate. Beryllium
The optimisation of silicon carbide grinding has been carried out using genetic algorithms to obtain a maximum MRR with reference to surface finish and damage. The grinding o The efficient grinding of high performance ceramics involves the selection of operating parameters to maximise the MRR while maintaining the required surface finish and limiting surface damage.

The dielectric strength of silicon dioxide, [math]SiO_2[/math] is about 10 MegaVolts/cm which works out to 1000 V/micrometer. Thin films are on the order of 0.1 micrometers and should therefore have a breakdown of about 100 V. This is rarely achie
Silicon Carbide whiskers have been synthesized using silica sol and activated carbon as reagents via microwave heating without the presence of any of the alysts, such as Fe , Ni , and Al etc.. The synthesized whiskers were separated and concentrated from the as‐synthesized products using the gravity concentration process.

BLOk provides an alternative to silicon nitride films, enabling chipmakers to reduce the dielectric constant (k) of their overall copper damascene structures to achieve faster, more powerful devices. Silicon nitride (SiN) films are currently used as a copper barrier and etch stop in coination with low k dielectrics to form insulating film "stacks" between the chip''s copper circuitry.
Silicon carbide, chemical formula SiC, is a covalent bond material. C and Si belong to the same family, all have a tetravalent bond, while Si also has metal properties. Its structure has the mesh shape and body shape and has high strength in nature, so the properties of silicon carbide material include high-temperature strength, wear-resistant, corrosion-resistant, high thermal conductivity
We''ve been working on making this our master list of dielectric constants on the Microwaves101 web site, so we have started adding ceramics and semiconductor substrates to the original list.
