Mechanical and tribological properties of a sintered glass-ceramic compared to granite and porcelainized stoneware

Mechanical and tribological properties of a partially crystallized sintered glass-ceramic were compared to two commercial floor tiles: black granite and porcelainized stoneware. Mechanical properties, hardness and elastic modulus were evaluated by instrumented indentation. Friction coefficient and wear characterization were evaluated using a reciprocating ball-on-flat tribometer in two controlled environments: air with relative humidity of 53% and under running water at 23 °C. The sintered glass-ceramic and porcelainized stoneware presented similar mechanical and tribological properties. Regarding the mechanical and tribological properties, the results suggest that this glass-ceramic is suitable to be used as industrial tile.

► Mechanical and tribological behavior comparison among three different ceramic materials.
► Glass-ceramic is produced from sintered commercial soda-lime glass.
► Sintered glass-ceramic show similar properties compared to the porcelainized stoneware.
► Glass-ceramic could be used as commercial tile with high mechanical and wear resistance.
