Abstract: In order to achieve the application of lepidolite tailings in foam ceramics from Yichun,Jiangxi,the foam ceramics were prepared using lepidolite tailings as the main raw material,supplemented by fly ash,kaolin,and CaCO3 ,with SiC as an efficient foaming agent. The high-temperature foaming technique was employed to systematically investigate the effects of sintering temperature,holding time,CaCO3 content,SiC addition,and tailing proportion on the properties of the foam ceramics. The results showed that with ratio of tailing ,fly ash,kaolin,and CaCO3 of 85 ∶10 ∶5 ∶5,along with 0. 35% externally added SiC, the foam ceramics sintered at 1 240 ℃ for 40 min exhibited a compressive strength of 9. 8 MPa,porosity of 81. 62%,density of 0. 528 g / cm 3 ,and average pore size of 1. 95 mm. These performance indicators meet the application requirements for lightweight building materials and filter materials. The study clarified the synergistic mechanism between key process parameters and raw material ratios,providing theoretical support and technical pathways for the large-scale efficient utilization of lepidolite tailings and the optimization of foam ceramic preparation processes.
