Graphite – Structure, Properties and Types
Graphite is a good conductor of electricity due to its free delocalized electron which is free to move throughout the sheets. Graphite is insoluble in organic solvents and water, this is because the attraction between solvent molecules and carbon atoms is not strong enough to overcome the covalent bonds between the carbon atoms in the graphite.
what is semiconductor ? | Yahoo Answers
2011/2/1· Dozens of other materials are used, including germanium, gallium arsenide, and silicon carbide. A pure semiconductor is often called an “intrinsic” semiconductor. The electronic properties and the conductivity of a semiconductor can be changed in a controlled manner by adding very small quantities of other elements, called “dopants”, to the intrinsic material.

Ceramics - their properties, manufacture, and everyday uses
2019/9/1· Examples include silicon carbide fibers in a silicon carbide matrix (SiC/SiC) with boron nitride at the interface between them—a material used in cutting-edge gas-turbine jet engines. Photo: Advanced ceramics: Silicon and carbon fuse to form silicon carbide powder (left), which can be made into a hard and hard-wearing ceramic called silicon carbide that can survive high temperatures.
FAQ: Benefits of copper vs aluminium conductors | Eland …
The difference in the conductivity means that a much larger size aluminium conductor needs to be used to match the conductivity of the equivalent copper conductor. Using a larger size conductor has the add-on effect of requiring a greater amount of insulation material to adequately cover the conductor and the extra cross-sectional size of the cable may be restrictive in certain appliions.
Suppliers of Silicon Alloys
Silicon is a metalloid; it has characteristics of both metals (shiny metallic appearance, strong) and non-metals (brittle, not a good conductor of electricity). After being isolated as an element it was originally called Silicium, the "ium" suffix denoting a metal in the same fashion as Aluminium.
Quick Answer: Is Cement A Ceramic Material? - Ceramics
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.
