Ans. (b)
Aluminiumoxide(Al2O3 )This is one of the natural abrasives found, and is also called
corundum and emery. However, the natural abrasives generally have impurities and, as a result, their performance is inconsistent. Hence the abrasive used in grinding wheels is generally manufactured from the aluminium ore, bauxite, Silicon carbide (SiC) Silicon carbide is made from silica sand and coke with small amounts of common salt.

Introduction:
In the field of abrasives, synthetic materials are widely used due to their superior properties and consistent quality. Synthetic abrasive materials are manufactured through various processes to obtain the desired characteristics for cutting, grinding, and polishing applications. However, not all abrasive materials are synthetic.
Explanation:
- Silicon Carbide: Silicon carbide (SiC) is a synthetic abrasive material that is widely used in grinding and polishing applications. It is extremely hard and has excellent thermal conductivity, making it suitable for high-temperature applications. Silicon carbide is often used in the production of grinding wheels, sandpapers, and cutting tools.
- Aluminium Oxide: Aluminium oxide (Al2O3), also known as alumina, is a synthetic abrasive material commonly used for cutting and grinding applications. It is hard, durable, and has good heat resistance. Aluminium oxide is widely used in the production of grinding wheels, sandpapers, and abrasive belts.
- Titanium Nitride: Titanium nitride (TiN) is not an abrasive material. It is a hard ceramic coating that is applied to cutting tools and other metal surfaces to enhance their performance and durability. Titanium nitride coatings improve the wear resistance of tools, reduce friction, and provide a gold-like appearance.
- Cubic Boron Nitride: Cubic boron nitride (CBN) is a synthetic abrasive material that is second only to diamond in terms of hardness. It is used for grinding hard materials such as hardened steels, superalloys, and ceramics. Cubic boron nitride is often used in the production of grinding wheels, honing stones, and cutting tools.
Conclusion:
Among the given options, aluminium oxide (Al2O3) is not a synthetic abrasive material. It is a naturally occurring mineral known as corundum. However, synthetic versions of aluminium oxide are widely manufactured and used as abrasives due to their superior properties. Silicon carbide, titanium nitride, and cubic boron nitride are all synthetic abrasive materials that are commonly used in various grinding and cutting applications.
