How is the chemical properties of quartz glass

  Quartz glass is an acidic material that, besides hydrofluoric acid and hot phosphoric acid, is inert to any other acid and is an excellent acid-resistant material. The degree of corrosion of the quartz glass by the alkali and the salt at room temperature is also extremely small, so the use of quartz glass in these reagents is not excluded.

  Transparent quartz glass has better chemical stability than opaque quartz glass because the latter has an increased surface area exposed to the corrosive liquid due to the presence of bubbles.


  Quartz glass is not hygroscopic and does not weather. Quartz glass is very sensitive to all alkali and alkaline earth compounds. The extremely slight traces of these compounds also contribute to the crystallization of quartz glass at high temperatures.
