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.Addition, high-energy ball milling can result in an effective doping with nanostructured carbon, which improves bc2 by impurity scattering. on the other hand, it is becoming more and more difﬁcult to obtain commercially amorphous boron (b) powder and the availability of high purity amorphous b is also limited in the market.
