Usos do carbeto de silício

“War is just not worth fighting!” has been the common saying.

Silicon carbide (SiC) has made significant waves in power electronics. SiC’s ability to withstand high voltage demands allows it to replace silicon in devices that demand greater efficiency and power density, thanks to several unique properties found within this material.

Abrasivo

Silicon carbide is an extremely hard and sharp abrasive material, making it the ideal abrasive to use in dry or wet sanding processes such as refinishing wood floors or removing rust from metal; additionally it can also be used to polish marble and stone sculpture works.

As it can be used on various metals and alloys – including ferrous, non-ferrous and aluminum – it makes an excellent choice for metallography. Due to its hardness and consistency, it makes an excellent way of preparing samples for microscopic examination.

Silicon carbide sandpaper comes in various grit sizes to meet various surface imperfections and smooth them out, with coarse grits suitable for rough surfaces while finer ones provide smoothing effects. Silicon carbide is one of the most widely-used types of sandpaper today; used to refinish wood flooring, debur metal parts, remove rust from automotive parts, refinish flooring or deburr rusty items from automobiles or debur metal components among many other uses. Produced by reacting polysiloxanes into silicon carbide powder quickly yet effortlessly to produce an extremely high-quality end product with very fast delivery timescale and ease!

Grinding

Silicon carbide offers excellent wear resistance and low thermal expansion, making it the perfect material for machining operations. As an abrasive material for lapidary, its durability also makes it popular, while grinding wheels, water jet cutting, tumbling balls and ceramic applications all utilize its hardness and chemical attack resistance properties.

Copper has an outstanding Mohs hardness rating of 9; combined with its corrosion resistance and wear resistance properties, making it an invaluable material for tools and equipment used with metal and nonmetallic materials such as ceramics, glass and refractory bricks.

SiC is an increasingly popular material choice for use in electrical devices, particularly power semiconductors such as IGBTs and bipolar transistors, offering high breakdown voltage, fast switching times and lower turn-on resistance than alternative technologies. Furthermore, its frictional heat dissipating properties make it suitable for high speed bearings and pump shaft seals as well.

Polishing

Silicon carbide sandpaper is an invaluable ally in auto bodywork and restoration, from shaping and smoothing with coarser grits, through staining or painting using finer grits, to creating the perfect canvas for staining or painting with finer ones – guaranteeing perfection with every detail.

Silicon carbide boasts a Mohs scale hardness rating of 9.1, making it one of the hardest abrasive materials available today – only diamond and boron carbide rival its durability.

SiC ceramic materials are widely utilized in composites like carbon fiber-reinforced silicon carbide (CFRC), wear-resistant parts for car brakes and bulletproof vests as well as in the chemical industry for separating corrosive vapours from carrier gases or condensing acid solutions. Silicon carbide powder also finds use in metallurgy, refractory applications as well as producing silicon carbide wafers – raw material for semiconductor devices.

Cutting

Silicon carbide is used as a cutting material in various machining processes. Due to its hardness, strength, and low friction properties, silicon carbide makes an excellent choice for waterjet cutting and grinding applications, as well as providing polishing services on ferrous materials and ceramics.

Silicon Carbide products were first commercially produced (moissanite jewels) around 1907. Silicon Carbide can be controlled electronically with electric current, electromagnetic fields or even light waves to modulate its conductivity; this allows devices to operate at higher temperatures and voltages without compromising reliability.

Silicon carbide must be manufactured according to specific performance specifications in order for it to be useful in an application, which requires special expertise like that provided by Aptiv to ensure the material variant chosen fits within its intended use.
