Silicon Carbide - Structure, Properties, and Uses of SiC
Silicon carbide is a very popular abrasive in modern lapidary owing to its durability and the relatively low cost of the material. It is, therefore, crucial to the art industry. In the manufacturing industry, this compound is used for its hardness in several abrasive machining processes such as honing, grinding, water-jet cutting, and sandblasting.
What Metal is a Good Conductor of Heat
In general, metals are shiny, reflecting most of the light that strikes them. They are malleable and ductile (that is, they will bend under pressure and are not brittle). They have a broad range of melting temperatures (e.g., mercury is a liquid at room temperature
Material of the month – silicon carbide | IOM3
Silicon carbide is a semiconductor and, like silicon, can be doped with trace amounts of other elements to form diodes, junctions and transistors. Semiconducting silicon carbide first found appliion as a detector in early radios at the beginning of the 20th Century.

Scotlight Direct Blog | How Light Emitting Diodes Work …
As silicon does not readily conduct electricity, and neither does the junction that has been created, a barrier is created between the n-type silicon and the p-type silicon. This is known as a depletion zone, due to the fact that it contains neither free electrons or holes.
The thermal conductivity of silicon | Electronics Cooling
For steady state thermal analyses at the board and system level, however, accurate values are not required, because the influence of the Silicon on the overall performance is limited. Remarkably, the thermal conductivity (in W/mK) defined in various papers and handbooks varies widely – 68.8, 83.7, 100, 125, 140, 153.46!, 157 – and often only one value at an unknown temperature is recommended.
Why is Silicon Used for Electronic Devices? - Wafer World
There are few things that are more complex than electronic devices. Despite this, the simple element silicon (Si) is the basis for most electronics today. Silicon, and the silicon wafers they are made into, power everything from supercomputers to smart phones to air microwave ovens.
