摘要

第四代硫系化合物Cu2ZnSnS4具有无毒、元素丰富、塞贝克系数高、导热系数低等优点，是热电(TE)材料的潜在候选材料。本研究以Cu、Zn、Sn和S粉末为原料，采用机械合金化法制备了Cu2ZnSnS4。为了研究铣削时间对Cu2ZnSnS4形成的影响，分别对铣削时间2、4、12和16 h进行了研究。结果表明，铣削12 h后Cu2ZnSnS4开始形成，铣削16 h后Cu2ZnSnS4完全形成。另外，经过16 h的铣削，得到了Cu2ZnSnS4纳米颗粒，其分布范围主要在50 ~ 60 nm。

SYNTHESIS OF Cu2ZnSnS4 BY MECHANICAL ALLOYING METHOD FOR THERMOELECTRIC APPLICATION

Quaternary chalcogenide Cu2ZnSnS4 is a potential candidate for thermoelectric (TE) application due to a number of advantages including containing only non-toxic and abundant elements, high Seebeck coefficient and low thermal conductivity. In this study, Cu2ZnSnS4 was synthesized using mechanical alloying method from Cu, Zn, Sn and S powders. In order to study the effect of milling duration on the formation of Cu2ZnSnS4, different milling duration of 2, 4, 12 and 16 h were investigated. As the results, Cu2ZnSnS4 was started to form after milling for 12 h. The formation of Cu2ZnSnS4 was completed after 16 h of milling. In addition, Cu2ZnSnS4 nanoparticles were obtained after 16 h of milling with the distribution mostly in the range of 50 - 60 nm.
