A safe and scalable continuous flow strategy for Wolff–Kishner reductions that employs methanol as the solvent has been developed. The use of low-cost hydrazine as the reducing agent in coination with a caustic base provides an atom-efficient, environmentally friendly method for the deoxygenation of aldehydes and ketones to alkanes. Because of the required harsh and corrosive reaction
Silicon carbide (commonly referred to by its chemical formulation of SiC) is a chemical compound comprised of silicon and carbon that results in extremely hard (9 on the Mohs scale) iridescent crystals. CARBOREX ® grains and powders offer superior properties such as low density, low thermal expansion, oxidation resistance, excellent chemical resistance, high thermal shock resistance, high
Silicon forms two types of oxygen-containing silanes, namely, the siloxanes and siloxens. Silicon reacts with nitrogen at temperatures above 1000 C. The nitride Si 3 N 4 is of great importance. It resists air oxidation even at 1200 C.

Porcelain An ancient type of ceramics that developed in China as early as the Shang dynasty of 1600–1046 BC. Porcelain comes in many varieties that are based on heating a clay mineral known as kaolin in a kiln, a type of oven. Properties Strong, hard, durable
4600 Silicon Drive Durham, NC 27703 Abstract- A compact circuit simulator model is used to describe the performance of a 2 kV, 5 A 4-H silicon carbide (SIC) power DiMOSFET and to perform a detailed comparison with the performance of a widely used
Silicon Carbide - Is a bluish-black material created by fusing silica and coke. It is in the same family as Ceramic (due to the Silica), but has much better lubriion qualities and is harder. The most common silicon carbide used in a mechanical seal is reaction-bonded silicon carbide.
Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON
In composition, it is silicon carbide and is manufactured by fusing a mixture of high purity sand, coke, and sawdust. It was first manufactured in 1890 in an attempt to produce artificial diamonds. At present, it is manufactured by using a very high current through of an electric arc at 2482 Centigrade.

Worth knowing: Properties of Silicon Carbide (SSiC / SiSiC) Low density (3.07 to 3.15 g/cm 3) High hardness (HV10 ≥ 22 GPa) High Young’s modulus (380 to 430 MPa) High thermal conductivity (120 to 200 W/mK) Low coefficient of linear expansion (3.6 to 4.1x10-6 /K at 20 to 400 C)
Silicon carbide has two similar crystalline forms, which are both related to the diamond structure. Boron carbide (B 4 C), on the other hand, has an unusual structure that includes icosahedral boron units linked by carbon atoms. In this respect, boron carbide is
Aluminum-(Silicon Carbide) is a metal-ceramic composite material consisting of silicon carbide particles dispersed in a matrix of aluminum alloy. It coines the benefits of high thermal conductivity of metal and low CTE (coefficient of thermal expansion) of ceramic.

Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique réfractaire ultradure semiconductrice synthétique, qu''on peut trouver dans la nature sous la forme d''un minéral très rare, la moissanite.Grâce au procédé Acheson, depuis la fin du XIX e siècle, on sait produire industriellement de la poudre de carbure de silicium, qui servit d''abord comme abrasif.
