| 摘 要： | 在水合法制备针铁矿过程中添加HBO3,对合成的样品作红外光谱和比表面积分析.结果表明,共沉淀法合成的样品在1343 cm处有特征吸收峰,说明在针铁矿形成过程中,如果有H3BO3参与,则形成的氧化铁中存在Fe-O-B键结构,可能在氧化铁内部有一种新硼铁化合物生成.比表面积测定表明,含B氧化铁比表面积增加4倍以上,反映了氧化铁与H3BO3并非机械混合物,其表面性质因为Fe与B反应而发生改变,B阻止氧化铁向高聚合态转变.

| Abstract: | IR spectral characteristics of goethite and ferric oxide synthesized with boric acid coprecipitation method showed that compared to goethite, Boron-containing ferric oxide displayed a peak at 1343 cm-1 in IR spectrum, suggesting that Fe-O-B bond existed in the material. Specific surface area of the material was 4 times more than that of goethite, implying that B hinders polymerization of ferric oxide. |
