Judd–Ofelt parameters were calculated to optimize the glass composition, rare-earth doping concentration, and dehydration processing conditions. Under excitation from a 980 nm LD laser, the Er³⁺/Yb³⁺ co-doped phosphate glasses exhibited strong fluorescence at 1.5 μm.

The Yb³⁺ ion demonstrated strong absorption across the 800–1100 nm spectral range. The emission spectra of Yb³⁺ and the absorption spectra of Er³⁺ overlapped significantly, facilitating efficient energy transfer from Yb³⁺ to Er³⁺.

Aluminum-based heat storage ceramic balls (HSCB) are widely used in high-temperature industrial kilns, but they have a problem of weak TSR. A similar situation existed in the HSCB with corundum and Mg-Al spinel phases in our previous research. In this study, corundum-spinel-mullite HSCB was prepared using pre-treated secondary aluminum dross (SAD) as the main material at low roasting temperature. The effects of mullite content on the mechanical properties and microstructure of the HSCB were studied. Mullite whiskers were cross-distributed with corundum and Mg-Al spinel, which benefited the TSR. With the increase of mullite content, the structure of the HSCB gradually became loosely, the TSR increased and then decreased slightly, and linear crack density increased. When mullite content was about 25 %, the comprehensive performance of HSCB performed perfectly. Under the optimal conditions, the coefficient of thermal expansion of the HSCB was only 5.70 × 10⁻⁶ K⁻¹, the thermal conductivity reached 3.35 W/(m·K) and the TSR was 34 times.
