Li2CO3-Fe2O3-ZnO materials were prepared by mechanical mixing with a lignin binder and thermal treatment. The variation in the surface structure and exothermic properties of Li2CO3-Fe2O3-ZnO materials for different treatment temperatures was investigated. The Li2CO3-Fe2O3-ZnO materials treated at 1200 °C showed the highest compressive strength of 2014 kPa and exothermic performance of 251 °C after treatment for 60 min. More importantly, the moisture content of the sludge augmented by Li2CO3-Fe2O3-ZnO reduced from 55% to 1.7% within 10 min. These results indicated that Li2CO3.Fe2O3. ZnO-based materials enhance the efficiency of sludge drying during microwave heating.
