Compound / Abrasive Type
   Abrasive Grain Type:       
   Your choices are...         
   Aluminum Oxide       Aluminum oxide is the most commonly used industrial mineral today. It occurs naturally in the form of the mineral corundum; however, this mineral is only used as a commercial abrasive in emery. Fused aluminum oxide is produced synthetically by melting bauxite and additives in an arc furnace to form fused aluminum-oxide ingots, which are later crushed and sized. Fused aluminum oxide is also produced synthetically by chemically purifying the various types of fused aluminum oxides, which are distinguished by the levels of chemical impurities remaining in the fused mineral. Titanium and chromium oxides are typical additives. Other techniques start with treating bauxite ore with a sol-gel process to create alumina that is sintered to an extremely-fine crystalline structure. Fused aluminum oxide is available in several variations, depending on composition and processing. Examples include white (high purity), brown or regular (titanium oxide modified), and pink (chromium oxide additions). Titanium oxide additions can toughen the abrasive and enable the heat-treating process, which changes brown aluminum oxide to a blue-colored grain as TiO2 precipitates form. Aluminum oxide abrasives are also produced with chemical precursors and precipitation, calcination and/or sintering processes. Calcined or platelet aluminas as used in fine-grit or polishing applications. Sol-gel aluminum oxide is produced by using chemical ceramic technology. These high-performance abrasives are usually referred to as "ceramic abrasive grains" in order to distinguish them from lower-performing forms of fused aluminum-oxide.  
   Boron Carbide       Boron carbide (B4C) is a very hard abrasive, with hardness second only to cubic boron nitride (CBN) and diamond. Boron carbide grains are very friable and, as a result, used mainly in bonded wheel dressing and the loose abrasive finishing of tungsten carbide or other hard alloys. 
   Ceramic       Ceramic abrasives usually consist of aluminum oxide with or without additional modifiers. They are produced in a sol-gel and sintering process. The ceramic processing method results in a hard, dense abrasive with an extremely-fine crystal size and outstanding grinding performance on a variety of workpiece materials. 
   Cerium Oxide       Ceria abrasives consist of cerium oxide and are used in fine polishing and lapping applications, especially in glass and optical components. 
   Diamond       Synthetic diamonds are produced in a high-temperature, high- pressure anvil press. Diamond is a superabrasive grain with the highest known hardness and a cubic crystal structure. Diamond is used for grinding nonferrous metals, ceramics, glass, stone, and building materials. It is not useful in grinding steel or ferrous alloys because the carbon or diamond readily dissolves or reacts with iron. Diamond pastes are useful in ferrous polishing or lapping applications in which heat and reactivity are not a factor.  Diamond is susceptible to oxidation at higher temperatures. 
   Garnet       Garnet is a natural silicate mineral made of almandite and pyrope. It is mined from igneous mineral deposits, or in concentrated pockets of alluvial deposits of old riverbeds. Garnet has the general chemical formula of Fe2O3Al2 (SiO4)3. The iron and aluminum are partially replaceable by calcium, magnesium and manganese. 
   Silica       Abrasive compounds are based on silicon dioxide or silica. Fumed silica-based CMP compounds are often used in semiconductor or silicon-wafer polishing and planarization applications. A pure silica CMP compound does not impart poisons or impurities into the wafer fab process. Typically, fumed or amorphous silica abrasives are chosen because crystalline silica is considered to be a carcinogen. 
   Silicon Carbide       Silicon carbide (SiC) is a synthetic abrasive that is harder than aluminum oxide, but more friable than fused aluminum-oxide grains. Typically, silicon carbide is applied to nonferrous metals such as brass, aluminum, or titanium. The high solubility of carbon and silicon in iron would cause a reaction between the silicon carbide and iron-base alloy, resulting in poor grinding performance. Levels and types of impurities distinguish the green and black forms of silicon carbide. The sharp and easily fractured abrasive grains can be used for abrading non-metals such as stone, glass, wood, and leather. Like diamond, silicon carbide is susceptible to oxidation at higher temperatures. 
   Tin Oxide       Tin oxide is an abrasive consisting of tin oxide. It is often used in polishing and lapping applications for glass and optical components. 
   Zirconia       Alumina-zirconia abrasive grains consist of a fused alloy of aluminum oxide and zirconium oxide. NorZon® is a widely used variation from the Norton Company. It consists of a fused and quenched eutectic mixture of aluminum oxide and zirconium oxide. The resulting fine structure and higher hardness contributes to improved grinding performance on stainless steel, titanium, and other exotic metals.

Grit Size
   Grit Size:       Grit size applies to products with abrasive grains that are held in a matrix, or that are bonded to a surface (e.g., coated abrasives, MSL superabrasives, vitrified grinding wheels, dressing sticks, honing stones or grit dressers). Grit sizes are based on ANSI, FEPA, JIS or proprietary grading-system standards. These grading-system standards define a grit size through specified upper and lower limits at certain points in the size distribution. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
