Glass Corrosion

Last updated: August 6, 2018

What Does Glass Corrosion Mean?

Glass corrosion is the deterioration of glass and its critical properties due to electrochemical reactions of the exposed material's surface with the surrounding environment. This can lead to deterioration and material failure.


Corrosionpedia Explains Glass Corrosion

Glass is a solid composed of deposited films of silicon dioxide and additives. It is generally assumed (incorrectly) that glass does not corrode or degrade. However, glass will corrode under certain conditions, such as the following:

  • Acid chemical attacks, including reactions involving hydrofluoric acid and phosphoric acid
  • Water attack or immersion for prolonged periods of time
  • Alkaline chemical attacks, often resulting in complete glass deterioration

Glass is particularly susceptible to two types of aqueous corrosion: static and dynamic. This is due to its tendency to molecularly attract and retain moisture.

Glass corrosion can be prevented by chemically treating its surface prior to use and periodic preventative maintenance activities. It is also vital to ensure that the correct type of glass is used for the correct corresponding application and environment.
