Can someone indentify the process by which a nitric/hydroflouic based solution is developed and maintained. Sounds simple enough - but the materials are reactive and I am wondering if there are alternatives (ammonia bi-fluoride, I.E.)?

Ammonium bifluoride is often used to supply the fluoride ion because of safety problems with HF. A typical solution is 25% Nitric acid + 8 oz/gal ammonium bifluoride.
