Surface chemical studies on zinc phosphate glasses were carried out with an ammonia probe using FTIR and XPS. Low softening point zinc phosphate glasses can be co-extruded with high softening point polymers to form polymer filled blends. NH3 reacts with P-OH groups to form bound NH4+ and with the zinc ions to form coordinately bound NH3. Bulk nitridation reactions, forming various P-N bonds to >100nm, occur concurrently.
