Quartz crystals are oxide minerals with the trigonal or hexagonal system, whose cell parameters are: a = 4.916 Å, b = 4.916 Å, c = 5.405 Å. The Si-O bond angle in α-quartz is 144° and the bond length is between 0.16101 and 0.16145 nm (Götze, 2009). The different types of quartz crystals are shown in Table 1.
