1. Structure of quartz glass and quartz crystal

Quartz crystal is characterized by a well-ordered crystalline structure composed of SiO2 molecules, exhibiting distinct crystal morphology and crystallographic plane. In contrast, quartz glass is an amorphous material with a disordered arrangement of SiO2, lacking regular crystalline morphology and crystallographic plane.

 

  1. Hardness and abrasionresistance of quartz glass and quartz crystal

Quartz crystal possesses significant hardness, rated at 7 on the Mohs scale, which confers exceptional abrasion resistance. Conversely, quartz glass has a hardness value of approximately 6.5, rendering it more susceptible to abrasion and scratching.

 

  1. Transparency and optical propertiesof quartz glass and quartz crystal

Quartz crystals exhibit high transparency along with favorable optical properties such as a large refractive index, minimal scattering, and low dispersion. These characteristics make them ideal for the fabrication of high-precision optical components. Although quartz glass displays slightly lower transparency and a reduced refractive index compared to quartz crystals, it remains suitable for applications in manufacturing glass products that require high temperature resistance, high pressure resistance, and high strength.
