In this work we demonstrate that high-energy ball milling process can be used to synthesize SnSb2Te4 without surfactant and further annealing. Milling parameters such as ball to raw material ratio (5:1) and milling time (2h) were determined to be suitable for synthesizing microplatelets of SnSb2Te4. The powders after
