摘要
对菱铁矿进行空气环境下的热处理,利用SEM等手段对其形貌变化特征进行研究,结果表明,随着热处理温度的升高,其菱面体晶形不随内部结构的改变而改变,同时,样品的颜色由青灰色转变为黑色,最终出现红褐色,并且在一定温度下,会出现分层现象。分层现象与热处理条件及样品本身的结构特征密切相关。
Siderite is heat-treated in air condition, the photography of SEM shows: though the microstructure of products has changed with the temperature increasing, the crystal shape has been keeping the rhombohedron as same as original shape. Meanwhile, the colour of products changes from grey to black, finally to redbrown. The phenomenon of separate layer is observed at 480 -600℃, which is mainly relate to heated temperature, keeping time and the structure of sample.
