Implication

Investigates the influence of lead on glass durability and devitrification in oxide glasses, indicating potential applications.

Key Points

  • The aim is to assess how lead concentration affects the chemical durability and devitrification of specific oxide glass compositions.
  • Analyzed glasses with compositions yPbO-(1-y)[xMoO3-(1-x)P2O5] for varying y (0-0.3) and specific x values (0.5, 0.67).
  • Conducted leaching tests across different pH levels and dissolution times using ammonium acetate solutions.
  • Used X-ray diffraction to analyze the crystalline structure of the glass post-devitrification.
  • Found that lead oxide (PbO) increases the chemical durability of the glasses, particularly up to 30% PbO concentrations.
  • Observed linear mass loss over time during leaching regardless of the glass composition.
  • Identified the formation of Pb(MoO2)2(PO4)2 in the crystalline glass structure.
