Abrasive Grain Type

	Abrasive Grain Type:
	Your choices are...
	Aluminum Oxide		Aluminum oxide is the most common industrial mineral in use today. Fused aluminum oxide is produced synthetically by melting bauxite and additive in an arc furnace to form a 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 are distinguished by the levels of chemical impurities remaining in the fused mineral. Titanium and chromium oxides are typical additives. Other techniques to make industrial abrasive start with treating bauxite ore with a sol gel process to create alumina that is sintered to produce with an extremely fine crystalline structure typical of the sol gel or Seeded Gel products available by Saint Gobain Abrasives. Fused aluminum oxide is available in several variations depending on composition and processing such as white (high purity), brown or regular (titanium oxide modified) and pink (chromium oxide additions). Titanium oxide additions can toughen the abrasive and enable 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 in using chemical ceramic technology, but this abrasive has very high performance and is usually referred to as Ceramic abrasive grain to distinguish the grain from lower performing fused aluminum oxide.  Aluminum oxide occurs naturally in the form of the mineral corundum, but the mineral is not used as a commercial abrasive except as a component of emery.
	Ceramic (e.g., Norton SG®, Norton Quantum®)		Ceramic abrasives typically consist of aluminum oxide with or without additional modifiers produced using a sol-gel and sintering process.  The ceramic processing route results in a hard, dense abrasive with an extremely fine crystal size and outstanding grinding performance on a variety of workpiece materials. Norton SG® and Norton Quantum® are examples of ceramic alumina grain manufactured by the Saint-Gobain Group.  The patented alumina seeding process used in manufacturing Norton SG® abrasive grain produces a sub-micron crystal structure resulting in superior performance.
	Silicon Carbide		Silicon carbide is a synthetic abrasive first developed in the late 1800s.  SiC is harder than aluminum oxide, but more friable than fused aluminum oxide grains. Silicon carbide is typically applied to nonferrous applications (brass, aluminum, titanium).  The high solubility of carbon and silicon in iron would result in a reaction of silicon carbide with the iron base alloy and poor grinding performance.  Levels and types of impurities distinguish the green and black forms of silicon carbide. The sharp and easily fractured abrasive grains for abrading other non-metals such as the stone, glass, wood, and leather. SiC, like diamond, is susceptible to oxidation at higher temperatures.
	Zirconia (e.g., Norzon®)		Alumina-zirconia abrasive grain consists of a fused alloy of aluminum oxide and zirconium oxide.  NorZon® is widely used variation proprietary to Norton Company, which consisting 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.
	Superabrasive - Diamond		Synthetic diamond is produced synthetically in a high temperature, high pressure process anvil press. Diamond is 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. Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron.  Diamond pastes are useful in ferrous polishing or lapping applications where heat and reactivity are not a factor.  Diamond is susceptible to oxidation at higher temperatures
	Superabrasive - CBN		Cubic boron nitride (CBN) is superabrasive grain with hardness second to diamond and a cubic crystal structure.  CBN provide super grinding performance on carbon and alloy steel.  Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron.  CBN is produced synthetically in a high temperature, high pressure process anvil press a process similar to synthetic diamond production.
	Tungsten Carbide		Crushed tungsten carbide grit is utilized in metal bonded products for abrasion of tough materials such as composites, fiberglass, reinforced plastics, rubber and other specialized materials.
	Other		Other specialty, proprietary or patented abrasive grain, grit or abrasive material.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
