Preventing HF from attacking glass from Inorganic Ventures
In this video Dr. Brain Alexander and Dr. Paul Gaines from Inorganic Ventures, discusses about the prevention of HF from attacking glass. When glass or quartz is exposed to HF, they are attacked to the degree depending upon the concentration of the HF and the type of glass or quartz.
It is the HF molecule that does the attacking; not the fluoride anion (F-1). There is absolutely no attack by neutral solutions of F-1upon any form of glass or quartz. It follows that solutions containing HF that are neutralized with a base to eliminate HF will not attack silicates provided that the HO-1concentration is not too high.
