Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3 N 4 is the most commercially important of the silicon nitrides when referring to the term "silicon nitride". It is a white, highmeltingpoint solid that is relatively chemically inert, being attacked by dilute HF and hot H

The relative permittivity, or dielectric constant, of a material is its (absolute) permittivity expressed as a ratio relative to the vacuum permittivity.. Permittivity is a material property that affects the Coulomb force between two point charges in the material. Relative permittivity is the factor by which the electric field between the charges is decreased relative to vacuum.
