  • Synthesis of SnSb2Te4 Microplatelets by High

    Abstract. In this work we demonstrate that high-energy ball milling process can be used to synthesize SnSb 2 Te 4 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 SnSb 2 Te 4.The powders after milling for various durations were characterized by X-ray
