Silicon Carbide (SiC): Properties and appliions | …
Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
Non-oxide Ceramics – Silicon Nitride (Si3N4)
Silicon nitrides (Si 3 N 4) feature an excellent coination of material properties. They are nearly as light as silicon carbide (SiC), but their microstructure gives them excellent thermal shock resistance and their high fracture toughness makes them resistant to impacts and shocks.
Oxidation resistance and electrical properties of silicon …
Because of its excellent thermal, mechanical and electrical properties silicon carbide is widely used for heating elements. Nevertheless these elements are affected by electrical ageing (increase of electrical resistivity during use). This phenomenon is generally attributed to oxidation but no satisfactory answer has been presently found to reduce its effects. The aim of this study is to
Doping (semiconductor) - Wikipedia
History The effects of semiconductor doping were long known empirically in such devices as crystal radio detectors and selenium rectifiers.For instance, in 1885 Shelford Bidwell, and in 1930 the German scientist Bernhard Gudden, each independently reported that the properties of semiconductors were due to the impurities contained within them.
