Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 ... It is a white, high-melting-point solid that is relatively chemically inert, ...
Hexagonal boron nitride, which adopts a layered structure, is a useful high-temperature lubricant akin to molybdenum disulfide. Nitride compounds often have large band gaps, thus nitrides are usually insulators or wide-bandgap semiconductors; examples include boron nitride and silicon nitride.
Melting point: 2,830 °C (5,130 ... Similar AGG-toughening effects have been reported in Silicon nitride (Si 3 N 4). [48] Silicon carbide is used as a support and ...
SiAlON gear (right) prepared from a billet (left) by forging at 1200 °C within 2 seconds. SiAlONs are produced by first combining a mixture of raw materials including silicon nitride, alumina, aluminium nitride, silica and the oxide of a rare-earth element such as yttrium.
Silicon oxynitride is a ceramic material with the chemical formula SiO x N y.While in amorphous forms its composition can continuously vary between SiO 2 and Si 3 N 4 (silicon nitride), the only known intermediate crystalline phase is Si 2 N 2 O. [2] It is found in nature as the rare mineral sinoite in some meteorites and can be synthesized in the laboratory.
Aluminium nitride (Al N) is a solid nitride of aluminium. It has a high thermal conductivity of up to 321 W/(m·K) [ 5 ] and is an electrical insulator. Its wurtzite phase (w-AlN) has a band gap of ~6 eV at room temperature and has a potential application in optoelectronics operating at deep ultraviolet frequencies.
Binary compounds such as tungsten carbide or boron nitride can be very refractory. Hafnium carbide is the most refractory binary compound known, with a melting point of 3890 °C. [8] [9] The ternary compound tantalum hafnium carbide has one of the highest melting points of all known compounds (4215 °C). [10] [11]
