Abstract

The bioresorbable 10CaO·35Na2O·55P2O5 glass was nitrided by melting the glass under anhydrous ammonia. The nitrided glasses were fiberized at about 720 °C in air. The dynamic and the equilibrium pH value of the glass increases with the increase of nitrogen content. The incorporation of nitrogen not only increases the glass transition temperature, but also improves the chemical durability and makes it easier to fiberize. Further more, the nitrided glass is more resistant to devitrification.
