研究了高能碾磨硫化砷As4S4对其相变的影响。描述了α -As4S4向高温β -As4S4的转变以及As4S4纳米粉末（16-48 nm）的形成。x射线衍射（XRD）和拉曼光谱证实了β - as4s4的存在。通过比表面积和粒径分布的测量对细颗粒进行了表征。(c) 2007 Elsevier Ltd.版权所有。
The effect of high-energy milling of arsenic sulphide As4S4 on its phase transition has been studied. The transition of alpha-As4S4 to the high- temperature beta-As4S4 as well as the formation of As4S4 nanosize powder (16-48 nm) has been described. The presence of beta-As4S4 has been proven by X-ray diffraction (XRD) and Raman spectroscopy. The fine particles were characterized by measurement of specific surface area and particle size distribution. (c) 2007 Elsevier Ltd. All rights reserved.
