Low-thermal-conductivity materials are ideal candidates for high-performance thermoelectric materials. CsAg5Te3 is a new metal-rich chalcogenide with an inherent low-thermal conductivity. However, due to its complex crystal structure, obtaining high-purity poses serious challenge. In addition, the high price of pure metals Cs, Ag, and Te leads cost traditional solid-state methods preparing CsAg5Te3. To address these issues, preparation nanostructured fiber morphology was carried out using low-energy-intensity scalable microwave method. The nanofibers were then assembled spark plasma sintering technology prepare bulk layered structure. lattice thermal conductivity material 0.19 W m–1 K–1, which almost lowest among state-of-the-art Finally, at 673 K, maximum zT value can reach ∼0.67. This study provides feasible pathway low-cost
