How to measure the oscillation frequency of quartz crystals ? Are quartz crystals just sitting there and oscillating or what ? And how to measure that ? Thanks
1) No; although it is possible to extract silicon from quartz, it will never be economic. An ore is a mineral from which one or more metals can be extracted economically. 2) color of quartz is due to impurities and hence any colour is possible. But pure quartz is colorless. 3) Being very hard, it is often use as abrasive, in making sand paper etc., or even to cut glass. Quartz is piezoelectric (it can generate electricity if pressure is applied at one end of the crystal) and this property if used in different electronic gadgets. It is also the primary constituent of silica sand, which is used to make glass.
