Abrasive

abrasive, sharp, hard material used to wear away the surface of softer, less resistant materials. Included within the term are both natural and synthetic substances, ranging from the relatively soft particles used in household cleansers and jeweler's polish to the hardest known material, the diamond. .

Abrasive Uses

Examples include emery and pumice. These abrasives are known for their durability and are commonly used in applications such as sanding wood or polishing metals. Synthetic abrasives, on the other hand, are man-made materials designed to mimic the properties of natural abrasives.
