摘    要:利用显微激光拉曼技术研究了山西耿庄天然纳-微米FeS2晶须的结构.发现FeS2晶须中有白铁矿和黄铁矿两种结构类型.较粗的藕节状、粗柱状、串珠状等不规则形貌为白铁矿相,直线状、平直、表面光滑的品须为黄铁矿相.耿庄FeS2晶须结晶生长早期以白铁矿相为主,中期是白铁矿和黄铁矿型结构共存,晚期以黄铁矿相为主.晶须生长过程有早期白铁矿结晶向晚期黄铁矿结晶转变的趋势.而且有黄铁矿包覆白铁矿的生长现象.FeS2晶须结构相变规律与形貌、形成时间和成分特点具有关联性.

关 键 词:拉曼光谱  FeS2晶须结构  相变规律

Abstract:FeS2 belongs to sulfide,including pyrite of isometric system and marcasite of orthorhombic system. The FeS2 discovered in Gengzhuang,Shanxi Province,was growing in the form of whisker. The study with scanning electron microscopy and electron probe show that the mineral components of FeS2 vary regularly. The structure of natural nano-micron FeS2 whisker was determined by micro-Raman spectroscopy. The results show that there exist two types of structure in FeS2 whiskers: pyrite and marcasite. Marcasite presen...
Keywords:Raman spectroscopy  FeS2 whisker structure  Phase transformation laws
