, yet survives 80% compression, 135° bending and 45° twisting without fracture. Repeated flame impingement, cyclic airflow scouring and ten-cycle ablation leave the back-face temperature below 400°C, evidencing reliable reusability. Because the "ceramic papermaking" route relies solely on gravity sedimentation and pH-triggered structural assembly, meter-scale or intricately patterned parts can be molded in hours, then dried at 80°C, avoiding complex sol-gel chemistry or high-temperature carbothermal synthesis. The same Seebeck-principle network further endows SFM with real-time temperature measurement (±10°C accuracy), integrating insulation and damage tolerance in one fire-strengthened sheet.
