Solution

An abrasive is a substance that is used to grind, polish or clean a hard surface by rubbing the two against each other. The substance used as an abrasive is always the harder than the one being polished. Carbon atoms in diamond forms a rigid, covalent three dimensional network where each sp³ hybridized carbon forms covalent bond with four adjacent carbon atoms, which makes diamond very hard . As diamond is the hardest of all natural substances and therefore the best candidate to be used as an abrasive.
