Silicon carbide (SiC) is an extremely hard, synthetically produced crystalline compound of silicon and carbon that finds applications across industries including refractory linings for industrial furnaces, high temperature petrochemical applications and semiconductor electronics substrates. Black silicon carbide is a tough yet friable abrasive material commonly used for processing low-tensile strength materials like glass and stone. Additionally, vitrified points and wheels can also be manufactured using this material. High-temperature strength Silicon carbide is one of the strongest ceramic materials and ideal for high temperature applications, such as chemical plants and mills. Its strength remains consistent up to 1,400 degrees C making it perfect for chemical plants and mills while it resists […]

Service technicians often feel that silicon carbide igniters are too fragile to handle safely, and are concerned that hand oils could wreak havoc with them. These ignitors are very reliable. When powered with 120 volts, they light up red hot and start the flow of gas into the furnace, lighting it up. Long Lifespan Hot surface ignitors for gas furnaces use glowing red silicon carbide heated by electrical pulses to ignite gas in newer furnaces, replacing older pilot light systems. While smaller than traditional spark plugs, they still serve their function of lighting up gas. With no need for constant burning pilot lights and reduced energy usage compared to earlier

Moissanite, an naturally-occurring form of silicon carbide (SiC), can be found as inclusions in meteorites, corundum deposits and rare kimberlites. Moissanite can also be created artificially using traditional sintering and hot pressing techniques in a laboratory environment. Moissanite gemstones used in jewelry are generally manufactured synthetically in laboratories. Here is how this remarkable gemstone comes to be. Brilliance Moissanite and diamond are similar in many ways, yet have many distinguishing characteristics that set them apart. One such characteristic is their brilliance – with moissanite often appearing brighter due to refracting light more, giving it more vibrancy than diamond. Moissanite shines thanks to its iridescence, flashing a colorless rainbow of light

Silicon carbide is an extremely hard material that lies somewhere between alumina and diamond on the Mohs scale, offering exceptional strength, corrosion resistance, durability, strength, high melting point and other engineering advantages that make it perfect for challenging engineering applications. Impurities called doping agents can also impart semi-conducting properties. Nitrogen and phosphorus doping creates an n-type silicon carbide structure; aluminum, boron or gallium doping creates a p-type silicon carbide structure. Bandgap The band gap refers to the difference in energy between a solid’s conduction and valence bands; the lower this gap is, the more conductive its material is. Band gaps play an essential role in how electricity conducts: they determine

Most hot surface igniters found on furnaces today are made from silicon carbide and run at 120 volts, but are prone to breaking if exposed to voltages outside their ideal range or handled roughly. Silicon nitride igniters are significantly tougher and longer-lasting than their silicon carbide predecessors, making them an attractive upsell option for customers looking to improve their system’s longevity and energy efficiency. They Heat Up Quickly Hot Surface Igniters (HSI) are used to regulate gas flow in furnaces, water heaters and other forms of heating equipment. Low-voltage high-current electricity passes through an igniter piece heated to 2500 degrees Fahrenheit before opening or sparking the pilot flame on gas

Silicon carbide is an extremely reliable wide band-gap semiconductor material. This allows devices made of it to operate at higher voltages, frequencies, and temperatures than conventional silicon devices. Monolayer SiC could be the catalyst to revolutionary advances in high-temperature electronics and power devices. It offers unmatched optical, mechanical, chemical and magnetic properties for unrivaled functionality in high temperature devices. Wider band gap The band gap of semiconductors refers to the space between their valence band and conduction band; this energy gap represents the minimum amount of energy a photon requires to excite electrons from one band to the next, producing electrical currents and thus operating them effectively. Band gaps play
