Chemical properties of
DURAN® Borosilicate Glass |

Chemical properties
The chemical resistance of DURAN® exceeds that of most metals and other materials even where long exposure times and temperatures in excess of 100°C are involved.
Exposure to water and acids only results in the leaching out of very small amounts of mainly univalent ions from the glass. The resultant very thin layer of silica, with few pores in it, that is formed on the surface inhibits further attack.
DURAN® is highly resistant to attack by water, neutral and acid salt solutions, strong acids and mixtures thereof, and also chlorine, bromine, iodine and organic substances. Only hydrofluoric acid, solutions containing fluorides such as ammonium fluoride, very hot phosphoric acid and strongly alkaline solutions attack the surface of the glass to an increasing extent at higher concentrations and temperatures.
