Abstract: Mullite-based ceramic slab tiles are widely used due to their excellent performance, but traditional preparation methods are energy-intensive. This study employed widely available raw materials (kaolin, potassium feldspar, albite, and quartz) and used Co 2 O 3 as a solar absorber to prepare ceramic tiles in both electric furnaces (EF) and solar furnaces (SF) for comparative analysis. Solar firing was conducted using a point-focusing system with an energy flux density (>1000 kW m−2), which achieved rapid heating (55 °C·min−1) and short holding (10 min) at the target temperature, reducing total processing time to approximately one-fourth of that required by EF. Results indicate that SF samples exhibit enhanced properties, attributed to photon-phonon coupling that excites Al-O-Si lattice vibrations, while Co 2 O 3 promotes photon absorption via d-d transitions. This synergy elevates oxygen vacancy concentration, accelerating ion diffusion and anisotropic mullite growth, with low-viscosity liquid phase aiding pore filling. Sintered at 1140 °C, the SF sample achieves water absorption of 0.09%, porosity of 0.23%, bulk density of 2.53 g cm−3, and bending strength of 54.2 MPa, meeting ceramic slab tile standards. This work provides theoretical and technical support for solar firing in ceramic manufacturing. [ABSTRACT FROM AUTHOR]
