WebBecause diamonds are very hard (ten on the Mohs scale ), they are often used as an abrasive. Most industrial diamonds are used for that purpose. Small particles of diamond are embedded in saw blades, drill bits, and … WebThe Mohs scale is based on relative scratch hardness of different materials; with talc assigned a value of 1 and diamond assigned a value of 10. [3] Mohs's scale had two limitations: it was not linear, and most modern abrasives fall between 9 and 10. [4] [5]; so, later scientists attempted to increase resolution at the harder end of the scale.
