Ceramic - Wikipedia

2019-4-23 · A ceramic material is an inorganic, non-metallic, often crystalline 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 chemical erosion that occurs in other materials subjected to acidic or caustic environments.

Sialon Ceramics – Silicon Nitride, Si3N4

At times, the silicon is replaced by aluminium with the corresponding atomic replacement of nitrogen by oxygen; this is done in order to satisfy valency requirements. The resulting ''solution'' has superior properties, both to the original pure solvent, syalon and to silicon nitride or Si3N4.

Polymorphs of silicon carbide - Revolvy

Many compound materials exhibit polymorphism , that is they can exist in different structures called polymorphs. Silicon carbide (SiC) is unique in this regard as more than 250 polymorphs of silicon carbide had been identified by 2006, with some of them having a lattice constant as long as 301.5 nm, about one thousand times the usual SiC lattice spacings.

Carbide - Wikipedia

2019-4-23 · In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by the chemical bonds type as follows: (i) salt-like, (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. Examples include calcium carbide (CaC2), silicon
