diamond is used as an abrasive .give reason?
Answers
Answer :-
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.
Diamonds Used as an Abrasive. Because diamonds are very hard (ten on the Mohs scale) they are often used as an abrasive. ... Small particles of diamond are embedded in saw blades, drill bits and grinding wheels for the purpose of cutting, drilling or grinding hard materials.
