    摘要: The addition of small quantities of V2O5 to low-softening potassium/lead phosphate glasses improves their water resistance. The use of larger quantities of V2O5 may give crystal formation in the glass. Potassium may be replaced by other alkali metals. Glasses having the composition (moles percent) P2O5, 46-61; PbO, 12-32; alkali metal oxide, 15-21; V2O5, 1.2-1.5; Group 2 metal oxides (excluding mercury), 0-6 are disclosed.
