2. Silicon carbide - Wikipedia

   en.wikipedia.org/wiki/Silicon_carbide

   Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor , it occurs in nature as the extremely rare mineral moissanite , but has been mass-produced as a powder and crystal since 1893 for use as an abrasive .

3. Sandpaper - Wikipedia

   en.wikipedia.org/wiki/Sandpaper

   Sandpaper. Abrasive material used for smoothing softer materials. Sheets of sandpaper with different grit sizes (40 (coarse), 80, 150, 240, 600 (fine)) Sandpaper, also known as glasspaper or as coated abrasive, is a type of material that consists of sheets of paper or cloth with an abrasive substance glued to one face.

4. Silicon carbide fibers - Wikipedia

   en.wikipedia.org/wiki/Silicon_carbide_fibers

   Silicon carbide fibers are fibers ranging from 5 [1] to 150 [2] micrometres in diameter and composed primarily of silicon carbide molecules. Depending on manufacturing process, they may have some excess silicon or carbon, or have a small amount of oxygen. Relative to organic fibers and some ceramic fibers, silicon carbide fibers have high ...

5. Polymorphs of silicon carbide - Wikipedia

   en.wikipedia.org/wiki/Polymorphs_of_silicon_carbide

   Many compound materials exhibit polymorphism, that is they can exist in different structures called polymorphs. Silicon carbide (SiC) is unique in this regard as more than 250 polymorphs of silicon carbide had been identified by 2006, [1] with some of them having a lattice constant as long as 301.5 nm, about one thousand times the usual SiC lattice spacings.

6. Sandblasting - Wikipedia

   en.wikipedia.org/wiki/Sandblasting

   Sandblasting, sometimes known as abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. A pressurised fluid, typically compressed air, or a centrifugal wheel is used to ...

7. Belt sander - Wikipedia

   en.wikipedia.org/wiki/Belt_sander

   Belt sander. A belt sander or strip sander is a sander used in shaping and finishing wood and other materials. [1] It consists of an electric motor that turns a pair of drums on which a continuous loop of sandpaper is mounted. Belt sanders may be handheld and moved over the material, or stationary (fixed), where the material is moved to the ...
