SILICON CARBIDE SiC Silicon carbide consists of the chemical elements silicon (like in sand) and carbon, and is very hard. Due to the good chemical resistance, silicon carbide can be applied very well under extreme conditions. ALUMINUM OXIDE Al₂O₃
All About Abrasives | American Machinist
Silicon Carbide Silicon carbide is a hard, sharp abrasive that has exceptional strength. However, due to its brittleness, it breaks down faster than aluminum oxide under heavy loads. Black silicon carbide is a semifriable, medium-density abrasive.
Black silicon carbide is harder than aluminum oxide, and is generally used for the abrasive wheel, slurry, refractory and ceramic industries. Silicon Carbide is special in the way it breaks down. As it breaks down into smaller particles, the media will expose new, sharp edges.

Passivation of SiC device surfaces by aluminum oxide - …
Silicon carbide material enables the devices to operate at higher electric fields, higher temperatures and in more radiation dense appliions than silicon devices. To be able to utilize the full potential of the SiC material, it is therefore necessary to develop passivation layers that can sustain these more demanding operation conditions.
9. Non-oxide ceramics
9.2 Silicon carbide SiC is the most widely used non-oxide ceramic material. It was first synthesized by Acheson in 1891 by heating a mixture of clay and carbon > 1600 C in a carbon arc (“carborundum“, a name still used today for abrasive and refractory grade
A Comparative Study on Flank Wear of Ceramic and Tungsten Carbide …
strength, hardness, and wear resistance of WC decrease, while its toughness increases because of the higher toughness of cobalt. Alumina based ceramic tools consist primarily of fine-grained, high-purity aluminum oxide. They are cold-pressed

Aluminum Oxide (Black Sintered), 16 through 150 Grits - …
Sinterblast is a high temperature calcined bauxite abrasive grain; 78 pecent aluminum oxide, 13 percent iron oxide. It is often used as to replace brown fused aluminum oxide due to its lower cost. Sinterblast is a very hard, tough abrasive, allowing it to be recycled many times, just like regular brown fused aluminum oxides.
Non-oxide Ceramics – Silicon Carbide (SiSiC/SSiC)
Worth knowing: Properties of Silicon Carbide (SSiC / SiSiC) Low density (3.07 to 3.15 g/cm 3) High hardness (HV10 ≥ 22 GPa) High Young’s modulus (380 to 430 MPa) High thermal conductivity (120 to 200 W/mK) Low coefficient of linear expansion (3.6 to 4.1x10-6 /K at 20 to 400 C)

Silicon Nitride Ceramic Cutting Tools used in Machining …
With the development of modern manufacturing technology, traditional carbide cutting tools have been unable to meet the production needs of new and difficult materials. Silicon nitride ceramic cutting tools are favored for their high hardness, strength, good fracture toughness, high-temperature oxidation resistance, and thermal shock resistance, which are widely used in hard cutting, high
Brown Fused Aluminum Oxide Powder - UK Abrasives
While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.
Hardness increased with silicon carbide or zirconium carbide content from 18 to 26GPa and 18 to 21.5GPa respectively. Thermal and mechanical loading of particle and RF transmission windows exposed to atmospheric pressure
Tips on Sanding Wood Floors With an Aluminum Oxide …
Only two of them are useful in sanding aluminum-oxide finishes: silicon carbide and ceramic grain. With silicon carbide abrasives, the grain macro-fractures, meaning that before the grain can dull, it breaks into smaller pieces that essentially resharpen the abrasive.

Aluminum-Silicon Alloys - Materials Database
Contact corrosion is especially poor in aluminum-silicon-copper alloys, but even copper-free alloys are worse in this respect than aluminum 99.8%. Machinability is poor, because the extreme hardness of the silicon coined with the relative softness of the matrix tends to wear the tools very rapidly.
