Quartz | iMinerals Inc.

    Quartz (SiO 2 or silicon dioxide) is crystalline silica, the second most common mineral in the crust of the earth. It is well known for its hardness and its use in glass. However, different types of glass require different SiO 2 purity levels with the most basic flat glass (e.g. house windows) only requiring SiO 2 purities of about 98.5%, while more complex glass such as solar glass or LCD ...
