Silicon Carbide Stone

Silicon carbide (SiC) is a dark green to black hard crystalline substance used in various industrial applications and as a symbol of strength and resilience.

Arkansas stones, made of Ozark novaculite, can be used to sharpen harder steels than most natural and synthetic stones. As they sharpen, they also polish for an exceptionally fine and smooth finish.


Silicon Carbide (SiC) is an advanced high-tech refractory material produced through high-temperature smelting of quartz sand, petroleum coke and salt in a resistance furnace. This rare mineral also exists naturally as Moissanite. SiC is commonly used for grinding and water jet cutting as well as sanding polishing and shaping applications.

Green silicon carbide stone boasts an extremely hard surface that makes it suitable for many grinding applications, including low tensile strength materials such as glass, ceramics and stone grinding as well as precision grinding of hard alloys and chilled steels.

Hardness in silicon carbide stones depends on their bond type. Vitrified bonds offer strong, resilient connections for precision grinding applications while resinoid bonds feature shock resistance for rough grinding applications.


Silicon carbide stones are highly hard abrasives used to grind metals, remove rust, and polish materials. Their hardness stems from their high carbon and silica content while their thermal expansion is low and strength is high, making this stone popularly chosen as an abrasive product.

These stones come in all sorts of shapes and sizes, each marked by its grit number. While sharpening stones can be used on all kinds of knives, sharpening stones are particularly helpful when sharpening specific types of blades like knives. There is a range of fine to coarse grit options available – making these stones especially versatile!

Silicon Carbide (SiC) is a black or dark green crystalline substance produced in laboratories or found naturally as the rare mineral moissanite, ranking 9.5 on Mohs’ scale of hardness, making it one of the hardest substances known. Due to its rigidity, high hardness, strong chemical bonding properties and low thermal expansion coefficient value it makes an excellent material choice for mirrors in astronomical telescopes as well as components used on spacecrafts.


Silicon carbide, more commonly referred to as carborundum, is a hard chemical compound composed of silicon and carbon. Commonly used as an abrasive material due to its excellent abrasion resistance and thermal conductivity properties; additionally it boasts low thermal expansion rates making it the go-to material for grinding semiconductors, ferrous metals, ceramics, and other materials; additionally it can also be utilized for machining operations or sandblasting processes.

Crystolon is a black or dark green crystalline material with a similar structure to diamond. Due to its hardness, durability and abrasion resistance it makes an excellent material for sharpening knives as well as producing sharpening stones, such as those sold by Crystolon and other manufacturers.

Prior research has demonstrated that various properties of silicon carbide can be affected by various factors, including its quantity and fineness. This study investigates their influence on various physical and mechanical properties for samples containing 25 mass % coarse or fine silicon carbide samples.


Silicon carbide is an affordable material used in numerous abrasive applications such as sandblasting and grinding, as well as being an important raw material for semiconductor production, as it can be ground finely to produce crystals with superior qualities for electronic devices. Production techniques for Silicon Carbide range from reaction sintering, hot pressing, microwave sintering and pressureless sintering – with each method producing different properties for final products.

Cost of silicon carbide stones varies dramatically based on grit, size, and material chosen. A diamond stone tends to be more costly than its aluminum oxide counterpart; however, due to faster cutting speed.

Silicon carbide (SiC) is a black or dark green crystalline material, often synthesized in laboratories or found naturally as moissanite, that has hardness and rigidity that make it suitable for large telescope mirrors such as Herschel Space Telescope mirrors. Furthermore, due to its low thermal expansion coefficient it makes an attractive material choice for spacecraft subsystems.
