Silicon Carbide Abrasive

Silicon carbide, more commonly referred to as corundum, is an extremely hard abrasive material used for grinding and polishing metal specimens.

SBM is more cost-effective than diamond and cubic boron nitride, yet maintains higher strength at elevated temperatures than many ceramic materials. Available in various grit sizes from coarse to fine, making it suitable for all stages of sample preparation.


Silicon carbide, commonly referred to as SiC, is one of the hardest common abrasive materials on earth – rivaled only by diamond, cubic boron nitride, and tungsten carbide in terms of hardness. Furthermore, SiC is highly dense with good heat resistance properties making it an attractive material for industrial applications.

Silicon carbide was first produced in 1891 by Pennsylvania inventor Edward G. Acheson using heated clay and powdered coke mixture heated in an iron bowl with carbon electrodes to produce green crystals that resembled diamond. While natural silicon carbide deposits are rare, mass production began around 1893. Today it comes in both black or green microgrit forms for pressing powdering purposes and as ready-to-press powder forms.

Silicon carbide’s high hardness makes it an attractive abrasive material for various metalworking and finishing applications, from grinding nonferrous metals and ceramics to cutting and polishing metals. Furthermore, silicon carbide abrasives tend to be cheaper than diamond grit and have lower tensile strengths – perfect for nonferrous metals and materials with weak tensile strengths such as nonferrous alloys.

Aluminium oxide may be less resistant to impact than conventional alumina abrasives, yet is significantly sharper and more durable than them. It makes a good choice for rougher surfaces that need aggressive cutting action such as rough concrete surfaces. Furthermore, MDF and cork materials such as MDF can benefit from its use as it provides extra aggressive cutting action.

Silicon carbide stands out from aluminum oxide as it can be recycled and reused without losing its abrasive properties. Furthermore, it can be mixed with other abrasive grains to enhance performance – for instance when combined with brown fused alumina (Al2O3) in bonded abrasives to increase toughness while still offering superior wearability.

No matter if you use abrasive grains for metal machining or finishing, it is important to understand the differences between these products so you can choose one suitable for your application. While their chemical makeup differentiates them, advances in particle engineering have yielded products with tailored performance capabilities such as alumina zirconia and ceramic alumina that may better meet your requirements.


Silicon carbide, also known as black silicon carbide or moissanite, is an extremely sharp material ideal for use as sandblasting media. Furthermore, its chemical resistance withstands attacks from acids and alkalis as well as attacks from molten metals and glass; combined with its hardness it makes an abrasive material of outstanding versatility and durability.

Abrasive blasting is the practice of shooting pressurized abrasives at high speeds across a hard surface to power away rust or remove old finishes from products. One popular form of silicon carbide abrasive material for this process is silicon carbide; due to its cost effectiveness and long-term properties.

Silicone carbide’s primary advantage lies in its ability to cut through hard materials such as cast iron and steel, with ease. Furthermore, it ranks second only to diamond as far as Mohs scale hardness is concerned; hardness of abrasive grains determines how much wear they can withstand before needing replacement.

To maximize silicon carbide’s effectiveness, manufacturers first form it into an angular grain shape. This creates numerous sharp cutting edges which enable fast and efficient cutting through of hard materials quickly and efficiently. Furthermore, its grains are friable – breaking down during use to expose more sharp cutting edges than originally planned.

Cooled and solidified to prevent undesirable crystalline structures from forming, the grains are then graded and classified by particle size for proper industrial standards compliance.

Aluminum oxide is another cost-effective alternative to silicon carbide abrasives that is often utilized instead. Aluminum oxide offers lower costs while still meeting nonmetallic surface needs; however, its durability can decline more quickly and it erodes more quickly compared to silicon carbide.

So it is essential that you choose the appropriate abrasive for your particular application. KLEEN BLAST stocks an extensive inventory of silicon carbide and aluminum oxide products in various sizes that we can help you select for your project.

Silicon carbide (commonly referred to as corundum) is a hard chemical compound composed of silicon and carbon. Naturally occurring as the rare mineral moissanite, mass production began in 1893 for use as an abrasive. Available either black or green depending on its intended application.

Silicon carbide features sharp, angular particles that make it effective for cutting applications, while being much harder and more durable than aluminum oxide – thus making it suitable for high-pressure situations. Black silicon carbide can be found in wheels and slurry abrasives while green silicon carbide works better as rough sanding material.

Silicon carbide abrasives may be extremely durable, yet still wear down faster than other abrasives. While this could pose problems when working on hard materials like stone or metal, its sharp edges provide quick removal of paint or coatings without harming surfaces.

Home repair and renovation projects require various tools and supplies, including sandpaper. Silicon carbide abrasive is often the preferred choice of DIY enthusiasts looking to restore furniture, renovate cabinets or prepare surfaces for painting; carpenters and craftspeople looking for an abrasive that can withstand hard use will often opt for this material instead.


Silicon carbide is a non-oxide ceramic with excellent chemical stability and thermal expansion coefficient; thus making it suitable for various abrasive applications such as polishing metals or metallographic specimens. Available both as granular and powdered forms of abrasives.

Silicon carbide can also be used as an abrasive in sandblasting, where it can be combined with aluminum oxide to achieve a finer, more polished finish. With higher hardness than aluminum oxide and sharper and more durable grains than its rival, silicon carbide makes for more effective cutting of harder materials like steel and stainless steel than its aluminum oxide counterpart. In addition, glass and plastic cutting is possible, though wood or other soft materials cannot be cut by silicon carbide alone.

Silicon carbide stands out among its counterparts because of its wide-ranging compatibility. This makes it an excellent choice for use in metallographic applications involving microscopic examination of metal samples; additionally, this material can also be utilized for grinding and sanding processes.

At present, there are three primary methods for creating silicon carbide abrasives for commercial applications: dry powder production with reaction bonding or sintered using carbon, silicon metal or boron carbide as its base materials are both viable approaches to creating this hard, tough and long-wearing material.

Silicon carbide is not only hard and durable, but it is also easy to grind and cut. Cutting with either a diamond blade or grinding wheel, it is used in industrial cutting applications such as machining, water-jet cutting and sandblasting; and can even be used to etch, deburr and polish metals and other materials.

Workers exposed to silicon carbide abrasive may be exposed to airborne dust particles that pose health hazards and cause breathing issues or lung damage. Therefore, those working in factories producing this abrasive should receive appropriate training and access to safety equipment to minimize fatigue and discomfort during production runs.
