Feb 10, 2015  Quartz samples with Al or Ge levels reaching values higher than 100 ppm will hardly be purified into commercial levels, i.e., with Al content lower than 20 ppm, because most of the Al content is intrinsically placed in the crystal lattice. Therefore, natural quartz with low lattice impurities is a highly valuable and rare mineral (Götze, 2009).
