Silicon carbide is a tetrahedral, crystalline solid that occurs naturally as the gemstone moissanite, but can also be produced synthetically.
Abrasive Applications
Silicon carbide is an extremely hard, durable abrasive material with numerous industrial uses. Its robust characteristics include high hardness, extreme heat resistance and chemical inertness – as well as being produced in different forms and grades for different uses. Crystalline silicon carbide can often be seen being used for abrasive blasting; scratching surfaces in preparation for painting or bonding operations as well as being utilized for sanding and grinding operations are some examples of its uses.
Silicon carbide granules are widely utilized by ceramic and glass industries for honing and lapping metal and ceramic components to achieve precise dimensions and smooth surfaces. Furthermore, silicon carbide serves as raw material in producing silicon tetrachloride used as an antioxidizing agent in steelmaking processes.
As a coated abrasive material, RBSC is often employed for wire sawing silicon wafers and producing grinding wheels, cutting tools and sandpaper. With high corrosion and oxidation resistance as well as its ability to resist alkalis and acids, the material makes an excellent lining material at elevated temperatures for refractories linings; alternatively it serves as an eco-friendly replacement for diamonds when manufacturing LEDs in blue, red, and yellow hues – potentially replacing diamonds when making LEDs; alternatively it also acts as an eco-friendly replacement when producing blue, red, and yellow LEDs – in other words diamonds won’t do!

Their custom shapes granules can be produced according to customer requests while their blocks / rods/ wear parts for semiconductor applications can also be produced from these sinters/granules in different purity levels (colorless, pale yellow & green being the highest purities).
This company produces Reaction Bonded Silicon Carbide (RB SiC) materials for steelmaking. Their RB SiC material serves as fuel in the BOF process and acts as an alternate energy source, increasing scrap-to-hot metal ratio and raising tap temperatures in mills experiencing temporary hot metal shortages.
Metallurgical Applications
Silicon Carbide (SiC) is a semiconductor-based material consisting of pure silicon and pure carbon, often doped with nitrogen, phosphorus or beryllium for use as an n-type semiconductor, or aluminum, boron or gallium for p-type semiconductor application. SiC boasts outstanding thermal conductivity and hardness properties which makes it suitable for applications involving high currents at elevated temperatures, or both.
Natural moissanite can only be found in trace quantities in certain types of meteorite, corundum deposits and kimberlite; virtually all silicon carbide sold today for use in metallurgy is synthetic. Metallurgical grade SiC is used as an effective de-oxidizer and promoter of nucleation during electric furnace production of gray, ductile malleable iron production as well as prolonging refractory life in steel foundries.
Black SiC is widely utilized for manufacturing durable and wear-resistent bonded and coated abrasives such as sandpaper, grinding wheels and cutting tools that offer durability and resistance to wear. It’s also found its way into electronics production thanks to its exceptional wear resistance and thermal conductivity properties. Miller offers both briquettes and grains of metallurgical grade SiC for industrial applications that suit different applications; our representative will assist in selecting the ideal product sourced from one of our many processing plants throughout North America reducing freight costs and storage requirements by source briquettes/grains from North American locations reducing freight costs and storage requirements by being shipped direct.
Electrical Applications
Silicon carbide semiconductors have long been used for electronic applications due to their superior ability in handling electricity more efficiently than their counterparts – making it a preferred choice in electronic designs. Their wide band-gap allows higher frequencies, minimizing power losses and heat generation while being extremely durable – an essential attribute in applications requiring consistent performance over extended time periods.
Silicon carbide has many advantageous characteristics beyond its electrical qualities; such as being chemically stable at high temperatures and resisting erosion, corrosion and thermal shock. Because of these properties, silicon carbide has become popularly employed in various abrasive products like grinding wheels and brake discs as well as structural and metallurgical industries.
Silicon carbide market growth will likely be driven by increasing semiconductor device demand. It can be utilized for various semiconductor applications, including MOSFETs and Schottky diodes; moreover, its properties make it ideal for telecom applications due to being capable of operating at higher frequencies than standard semiconductors while handling higher voltages more effectively.
Silicon carbide is a key component of electric vehicles, providing improved energy conservation and more effective battery management systems. Bosch-led Transform project aims to secure European supply chain for SiC technology ranging from raw materials all the way through finished SiC power semiconductors and battery management modules.
