How is glass made scratch resistant?

Published in Glass Technology 2 mins read

Glass is made scratch resistant primarily through the incorporation of materials that increase its surface hardness.

Methods for Enhancing Scratch Resistance in Glass

Several techniques and materials are used to make glass more resistant to scratches. The goal is to create a surface that is harder and less susceptible to damage from abrasive forces.

  • Material Incorporation:

    • Silica: Adding silica can increase the hardness of the glass matrix.
    • Cerium Oxide: Cerium oxide enhances the glass's resistance to scratching.
    • Titanium Dioxide: The inclusion of titanium dioxide also improves the hardness and scratch resistance. The incorporation of silica, cerium oxide, or titanium dioxide can significantly enhance the glass's hardness, making it more resistant to scratching. These modifications not only preserve the transparency and aesthetic quality of the glass but also improve its toughness.21-May-2024
