Chemical resistance of binary metaphosphate glasses
A study was made of the interaction between HF and H/sub 2/O on the one hand and binary metaphosphate glasses containing cations of groups I-III on the other. Chemical and x-ray phase analysis and IR spectroscopy were used. The resistance of the specimens to HF and H/sub 2/O was evaluated. The extent of HF corrosion was determined from the loss of mass per unit area of the surface after etching. The resistance to H/sub 2/O was evaluated after boiling the specimens in distilled water by the same determination. It was established that the chemical stability of binary metaphosphate glasses increases with the field strength of the modifying cation. The least stable in HF and H/sub 2/O are the alkali metaphosphates and the most stable are the metaphosphates of trivalent elements.
