Question

why is quartz suitable for use as an abrasive, involving it's structure?

Answer 1

Quartz is used as the abrasive material, because its hardness on the Mohs scale is equal to 7 This is a very hard material. Due to the fact that quartz crystals are very fragile in nature, it is found mainly in the state of fine-grained. The hardness of quartz is higher than the hardness of steel, so it is used in knife sharpening and polishing of metals.
