Abstract
A composition for a water soluble glass is described. The composition is unusual in that it contains no or very small quantities (up to 5 mole %) of alkali metal compounds. The composition typically comprises: P2O5: 30 to 60 mole %; CaO: 20 to 35 mole %; MgO: 15 to 25 mole %; ZnO: 0 to 10 mole %; and optionally may contain: Ag2O or Ag2O3: 0 to 5 mole %; and/or total alkali metal compounds (e.g. Na2O and/or K2O): 0 to 5 mole %. The composition is especially suitable for processing into water soluble glass fibers or wool.
