Product Description
Silicon Carbide (SiC) is a non-oxide ceramic material widely used for applications that demand both superior thermal and mechanical performance. SiC is commonly found in applications requiring hard surfaces with hardness; wear-resistant parts due to its hardness; refractories and ceramics raw materials for production purposes; semiconductor electronics due to its resistance against oxidation at higher temperatures and voltages; as a heat shield in jet engines, as electrical insulation, and as protection against ballistic projectiles.
Carborundum (SiC), commonly referred to as carborundum, occurs naturally as the rare mineral moissanite in very limited amounts. Most commercial SiC sold is synthetically manufactured using melting silica sand at high temperature with carbon as its fuel, then cooling and solidifying in an inert atmosphere. SiC’s crystal structure features covalently bound silicon and carbon atoms arranged close together with four coordination tetrahedra interlocked and stacked polar structures forming its close packed structures polar structures forming its dense structure for its hard chemical nature as well as its high melting point, low density and good toughness properties.
SiC is used extensively as an abrasive material in grinding and cutting applications, particularly suitable for processing materials with low tensile strength such as glass, ceramics, stone, cast iron and non-ferrous metals. Furthermore, SiC serves as raw material in the production of refractories, ceramics and advanced cutting tools and wear-resistant parts.
SiC is an ideal material for both abrasive blasting and water-jet cutting due to its combination of hardness, durability, low dust generation, and popularity as an abrasive in modern lapidary work due to its durability. Micron sizes of SiC abrasives allow precision surface finishing with superior abrasion resistance; furthermore it has become an essential ingredient in modern machining processes such as honing, grinding and water-jet cutting.
Copper’s corrosion resistance, low thermal expansion coefficient and hardness make it an excellent material for optical applications, such as telescope mirrors and coatings. Furthermore, its rigidity and stability make it an excellent component for creating lightweight protective armor and bulletproof vests with superior strength characteristics. Finally, its chemical inertness and thermal conductivity enable advanced filtration systems for hot gases and liquids.
Aplicații
Silicon Carbide (SiC), also referred to as Carborundum, is an extremely hard chemical composed entirely of silicon and carbon, forming an inert wide bandgap semiconductor material. Naturally occurring as moissanite mineral in rare deposits but mass produced since 1893 as powder and crystal for use as an abrasive. Doping can occur with nitrogen, phosphorus, beryllium aluminum and gallium to make different varieties of SiC semiconductors; in addition, large single crystal blocks may be sintered together before cutting into gems referred to as moissanite gems.
Silicon carbide powder finds widespread application across numerous industrial sectors, from ceramics and refractories to iron foundries and deoxidization in metallurgy. Due to its high melting point, excellent thermal conductivity and resistance to thermal shock it finds wide use as deoxidizer and in iron foundries while its powder can also be mixed with refractory materials for wear-resistant coatings on machine tools and dies; furthermore it produces hard ceramic materials with superior wear resistance such as rocket nozzles and gas turbine blades.
Silicon Carbide (SiC) is an invaluable material in power electronics applications. Its ability to withstand high temperatures, voltage levels and radiation helps produce more efficient and compact electronic systems – particularly those needing high power, such as space travel or electricity transmission. Alter Technology even developed blocking SiC diodes specifically tailored for operation in extreme space environments while remaining highly efficient.
But workers who produce or use carborundum abrasives run the risk of contracting a lung condition that resembles silicosis. According to studies, exposure to dust from these materials may cause diffuse interstitial pulmonary fibrosis which in turn leads to decreased lung function and an increase in cardiovascular problems – although workers’ risk can be reduced significantly by wearing respirators and not smoking cigarettes.
