Abstract:
Polymeric compositions having a polymeric component and an inorganic filler which undergoes a crystal (phase) inversion within the operating temperature range of the composition are provided. The present invention relates to a method for reducing the water sensitivity of particles of a crystallized phosphate glass. The particles are composed of P.sub.2 O.sub.5 and one or more cations selected from the group consisting of magnesium, cobalt, arsenic, zinc, iron, aluminum, and zirconium. The method includes nitriding the particles.
