摘要
通过实验合成出了碲金矿 ,并对其进行了 2 0 0℃、80℃温度下不同 p H溶液中的蚀变实验。对碲金矿及蚀变产物分别进行了 X-射线粉晶衍射、矿相显微镜鉴定及电子探针和光电子能谱分析。实验结果表明 ,在中性、偏酸性和碱性溶液的实验条件下碲金矿基本保持稳定 ,而在碱性稀溶液实验条件下可观测到少量含 Fe、 Te、 Au新相的生成及碲金矿表面氧化态碲的明显增加。
Calaverite has been synthesized by the author. The alteration experiments on the synthetic products are conducted in solution with different pH values at 200℃ and 80℃ respectively. All products are analysed by X ray powder diffraction,electron microprobe,XPS,reflecting microscope. In a dilute alkaline solution experiment the new phase with (Fe,Au,Te) bearing compositions is found and tellurium oxides on the synthetic calaverite surface increase greatly.
