Jeremy Clarkson – Silicon Carbide

Jeremy Clarkson is an English television presenter and writer, most famous for his appearances on Top Gear alongside Richard Hammond and James May. Additionally, he presented The Grand Tour series.

Silicon carbide is produced commercially as a hard abrasive and in ceramics, while naturally appearing as moissanite gemstone. Furthermore, silicon carbide has many applications including composite armour and ceramic plates used in bulletproof vests.

High Temperature Resistance

Silicon carbide is an extremely hard yet surprisingly ductile material with high melting point and boiling point values that makes it suitable for heating elements and furnace components, and even nickel superalloy turbine blades or nozzle vanes in gas engines, where high temperature resistance is key.

SiC is known for its high melting and boiling points, high electrical conductivity, resistance to corrosion and thermal shock as well as being an attractive semiconductor material with an extremely wide band gap compared to silicon. Due to these properties, interest has grown in developing power MOSFETs and IGBTs using SiC; however problems arising between silicon dioxide layers and crystallized SiC have hindered progress.

Silicon carbide was first employed as one of its earliest applications: lightning arresters for protecting equipment from lightning strikes on electric power lines. This material has a very high resistance until lightning raises line voltage above its threshold value, whereupon it begins conducting and allows any damaging bolt to pass harmlessly through a spark gap and down to Earth instead of disrupting power transmission lines.

Silicon carbide’s extreme hardness enables it to be utilized in cutting tools and grinding wheels. Furthermore, tungsten filaments made from this material have long been known for their color rendering qualities, low heat output levels and long lifespan.

Owing to its extreme rigidity and strength, cast iron is also a superb material for use in wear-resistant coatings and hard facings, boasting up to 400 times greater wear resistance than steel. Cast iron also forms abrasion-resistant linings in steam and hot water boilers as well as crucibles and furnace parts.

Clarkson first worked for his parents’ business selling Paddington Bear stuffed toys as a travelling salesman. This helped pay for his education at Repton School where he met fellow Top Gear presenters James May and Richard Hammond. Later he turned his talents towards writing for local newspapers and automotive publications such as Performance Car before turning full time journalist. Additionally he has published multiple books, such as his weekly articles for The Sunday Times.

High Strength

Silicon carbide’s extreme strength enables it to be used in numerous applications. From grinding and cutting abrasives, to grip tape materials for skateboards and production of high performance brake discs (such as those found on Porsche Carrera GTs), and sintered diesel particulate filters to being the primary material in high temperature furnaces – silicone carbide has numerous uses!

Silicon carbide’s strength enables it to be utilized in composite armour such as that created by Chobham armour company and bulletproof vest ceramic plates, while it is also widely used in manufacturing glass and ceramics. Pure silicon carbide exhibits low electrical conductivity; however, adding dopants may increase it significantly and its temperature coefficient varies from negative at room temperatures to positive when heated at higher temperatures, making it suitable for high-temperature heating elements.

Moissanite, or naturally occurring silicon carbide, can be found in very minute quantities in certain meteorites as well as corundum and kimberlite rocks; however, most moissanite sold commercially is synthetically produced.

Moissanite is an artificial diamond simulant with similar chemical composition to natural diamond, both being hard (9 on Mohs scale, as opposed to 10 for diamond). As well as being hard (9 compared to 10, comparable with diamond), moissanite can also be purchased in jewelery stores as an semi-precious gemstone alongside emeralds and sapphires. Moissanite can be birefringent, making it unsuitable for some optical applications; however this effect can be diminished by cutting along its optic axis of crystal.

Jeremy Clarkson is an English television presenter and journalist best known for his roles on the motoring shows Top Gear and The Grand Tour alongside Richard Hammond and James May. Additionally, he regularly contributes to newspapers such as the Sunday Times and Sun, has written multiple books on motoring topics, was born in Doncaster Yorkshire 11 April 1960 to parents who owned a travelling salesman business and sold Paddington Bear toys as a teenager to fund his Repton School education. Later studied journalism at Kent University before eventually becoming columnist for The Sunday Times.

Extreme Durability

Silicon carbide is hard and wear-resistant even in water environments, while remaining corrosion-proof for use in harsh conditions. With temperatures reaching 1400degC it can withstand, its thermal conductivity helps minimize power losses in switching devices while its low coefficient of expansion and lack of phase transitions provide high mechanical strength at higher temperatures.

Moissanite is a naturally occurring mineral found in minute quantities in certain meteorites and corundum deposits like kimberlite. Additionally, synthetic moissanite jewels have become popular as more affordable diamond alternatives due to its transparency and hardness (9 on Mohs scale versus 10 for diamond) with a refractive index between 2.65-2.69 (compared with 2.42 for diamond). Unfortunately it also shows strong birefringence characteristics which could impede optical applications.

Silicon carbide’s unique crystalline structure makes it a prime candidate for use in producing ceramics, metals and plastics, abrasives, grinding wheels and polishers, cleaning electronic components like microprocessors and semiconductors. Furthermore, its chemical compatibility makes it useful as an abrasive. Additionally, silicon carbide has also proven successful at cleaning electronic components like microprocessors and semiconductors.

Silicon carbide ceramic can be formed and adhered to various materials with ease, for instance steel wires forming carbon ceramic brake discs are often made out of silicon carbide molds. Due to its toughness and high thermal conductivity, silicon carbide makes an excellent material choice for use in cutting tools as well as being easily carved and polished into intricate architectural forms and structures.

Although many semiconductor executives lament slow demand and excess inventories, one segment appears to be rapidly expanding: silicon carbide power circuits for electric vehicles. This trend is spurred by the emergence of “mega-watt cars”, characterized by multiple power semiconductors with batteries boasting far higher energy density than previous hybrid cars.

Additionally, he regularly writes columns for The Sun newspaper as a columnist and hosts ITV game show Who Wants to be a Millionaire? and reality series Clarkson’s Farm on ITV.

Low Cost

Silicon carbide can be produced in large quantities at relatively low costs. It is produced as a coarse powder by heating silica sand and carbon together in an Acheson graphite electric resistance furnace between 1600-2500 degrees Celsius to form carborundum, commonly used to manufacture abrasives; naturally occurring as the rare gemstone moissanite.

Silicon Carbide is one of the hardest technical ceramics, making it highly durable. Additionally, it is corrosion-resistant and inert chemically, making it an excellent choice for applications where physical wear is the main consideration, such as coating brake discs on supercars. Furthermore, this material offers thermal conductivity of unsurpassed levels.

Aluminum boasts a wide band gap and high electric field breakdown strength, so it can withstand very high current levels without succumbing to degradation, making it an attractive alternative to silicon for use in power semiconductor devices like MOSFETs and IGBTs for high-power switching applications.

Silicon carbide is not only a hard and durable metal; it has many other applications too. Silicon carbide can be used as an abrasive, while also having applications in ceramics production or the manufacture of electronic components. Furthermore, it’s often included as an ingredient in high-pressure lubricants to reduce friction between moving parts.
