Whether it is conceived as an insulator or conductor, the electrical resistivity of Si3N4 is an important principle in its mechanical and thermal performance.

Silicon nitride is a rather expensive material, but it’s performance to cost benefit ratio is excellent in the applications where it can outperform the normally utilized materials with long life and very reliable low maintenance operation.

Silicon nitride particles were compared to the other commonly used orthopaedic biomaterials (e.g. cobalt-chromium and Ti-6Al-4V alloys). This study demonstrated that silicon nitride is an attractive orthopaedic biomaterial due to its minimal biological impact on human PBMNCs.

Silicon nitride is synthesised typically by the chemical reaction of metallic silicon and gaseous nitrogen. Parts are carefully pressed and sintered by well-developed methods that give rise to particular properties and therefore define the end applications.

The product is not flammable. Wear self contained breathing apparatus for firefighting if necessary.

The formula for nitride Ion is N-3.

The dielectric constants of sputtered Si-nitride dielectric films are roughly bounded by the dielectric constants of SiO (3.9) and SiN (7.4) [5, 12, 13].

Silicon dioxide, SiO2, is an amorphous material used in microsystems as a dielectric in capacitors and transistors; as an insulator to isolate various electronic elements; and as a structural or sacrificial layer in many micromachining processes.

The dielectric constant of Si3N4 ceramics was 7.1–7.2 before annealing and 6.3–6.4 after annealing at 2GHz [25]. The dielectric losses of produced ceramics are lower than the dielectric losses of commercial silicon nitride called IRBAS and Ceralloy [26].

Silicon nitride is a very important engineering ceramic which is available in several forms, each with their own unique properties. These include high strength, toughness and hardness, excellent wear resistance, corrosion resistance to many acids and alkalis and outstanding thermal shock resistance.

Silicon is a natural chemical element, silicone is a man-made product. The words are often used interchangeably but there are important differences. Whilst silicon is natural, silicone is a man-made polymer derived from silicon.

Silicon is used for electronic devices because it is an element with very special properties. One of it’s most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others. It is even the most common element in the Earth’s crust.
