Quartz is designated high purity when it contains not only less than 50 μg g −1 of impurities, which mainly comprise structurally bound trace elements (B, Li, Al, Ge, Ti, Fe, Mn, Ca, K, Na and P) in the quartz lattice, but also micro-inclusions of minerals and trapped fluids. HPQ is rare in nature and larger deposits even more so.
