Overview

Findings demonstrate enhanced properties of refractory materials in low-temperature sintering using modified limestone.

Key Points

  • Investigate the effects of sintering temperature and modified limestone content on corundum properties.
  • Used gamma-Al2O3 and activated limestone as raw materials.
  • Conducted sintering at 1600°C, 1650°C, and 1700°C.
  • Analyzed phase composition and material properties.
  • Achieved a maximum compressive strength of 218.03 MPa at 1650°C.
  • Established favorable apparent porosity of 13.31% with 1.11 wt.% limestone content.
  • Observed that increasing limestone reduced bulk density while maintaining high compressive strength.
