Essay On Silicon Carbide

Silicon carbide known as carborundum with a chemical formula of (SiC) it shows combination of silicon and carbon. It can be found in the mineral moissanite, which was first discovered in Arizona and has been mass-produced since 1893. It only can be machined using diamond grinding techniques relatively of high hardness values of applications as well as brittle material. It is important to recognize how difficult to machining silicon carbide as the hardness same like diamond. This is because, incorrect procedures can generate sub-surface damage and micro-cracks that lead to premature failure and affect to operating stresses in service. Usually, silicon carbide is produced by heating silica sand and carbon to the high temperatures using Acheson process in the Acheson graphite resistance furnace. It in the form of fine powder or a bonded mass that must be milled before can be used as a powder feedstock. After the silicon carbide in a powder form, the grains of the compound can be bonded together by

First application that silicon carbide powder was used is abrasive application. Moreover, it also widely used in application that required high hardness and strength such as ballistic protection, optic device, thermal technology, nozzle and seal ring of mechanical rings. The strong bond between atoms of silicon and carbon suitable for high elasticity, extremely low thermal expansion and high thermal conductivity applications, for example semiconductor electronic devices which growing industry nowadays. Silicon carbide known as ceramic armour, typically used for body armour and for the protection of the outer coverings of various type of vehicles. Usually, silicon carbide ceramic tiles were adhesively secured to the substrate then encapsulated in the outer cover. It also placed in a fabric pocket in bulletproof vest application (Park,
