Material such as sand, crushed chilled cast iron, crushed steel grit, aluminum oxide, silicon carbide, flint, garnet, of crushed slag used for cleaning or surface roughening
A finely divided, hard, refractory material ranging from 6 to 10 on the Mohs scale, used to reduce, smooth, clean or polish the surfaces of other less hard substances, such as glass, plastic, stone, wood etc Natural abrasive materials include diamond dust, garnet, sand (silica), corundum (Al oxide, emery), pumice, rouge (Fe oxide), & feldspar; the more important synthetic types are SiC, B carbide, Ce oxide & fused alumina Abrasives in powder form are used in several ways: (1) Applied directly to the surface to be treated by mechanical pressure or compressed-air blast, as in cleaning building stone(2) Affixed to a paper or textile backing after the particles have been coated with an adhesive(3) Mixed with a bonding agent such as Na silicate or clay, the particles being compressed into a wheel rotated by a power-driven shaft
 Any of a number of hard materials, such as aluminum oxide, silicon carbide, and diamond, that are powdered and carefully graded according to particle size, and used to shape and/or finish optical elements, including the endfaces of optical fibers and connectors  Note: For finishing the endfaces of optical fiber connectors, abrasive particles are adhered to a substrate of plastic film, in a fashion after that of sandpaper  The film is in turn supported by a hard, flat plate  The connector is supported by a fixture that holds it securely in the proper position for finishing  The grinding motion may be performed manually or by a machine  [After FAA]
A coarse material, such as wet or dry sandpaper that is used to rub against the surface to be altered in order to 1 )make it smooth 2 ) make it rough 3 ) remove the surface material
Any substance used for grinding, cutting, polishing, or sand blasting and sand carving The most popular being different textures of silicon carbide and aluminum oxide Such textures are known as GRITS

Material used for grinding, sanding, polishing or the wearing away of another material Aluminum oxide, garnet and silicon-based compounds are commonly used as abrasives for sanding and smoothing wood
A material used to sandcarve into a substrate Popular abrasives are Aluminum Oxide and Silicon Carbide For standard sandcarving 150 grit is recommended For photo etching 220 grit is recommended
An abrasive substance is rough and can be used to clean hard surfaces. a new all-purpose, non-abrasive cleaner. a rough powder or substance that you use for cleaning something or making it smooth
