Abstract
A lead-containing glass material of the type suitable for use in a wafer bonding process, wherein the moisture resistance of the glass material is increased by the presence of a lead phosphate coating on an outer exposed surface of the material, thereby acting as a barrier to reaction of moisture with the lead of the glass material. A source of reactive phosphate ions is applied to the glass material so as to spontaneously form the desired lead phosphate coating.
