Silicon (Si) is the second most chemical element in the earth's crust. Quartz is the most common form of silica, accounting for 12.6% of the earth's crust volume (Götze, 2009).And, quartz is mainly composed of silicon dioxide (SiO 2), which is widely used in both traditional basic industries and high-tech fields due to its stable physical and chemical properties (Haus, 2005, …
