【摘要】 介绍了人工合成八面体晶质铀矿的实验成果,并对合成的晶质铀矿样品进行了矿物学研究,获取了重要数据:合成的晶质铀矿样品最大颗粒为2.5mm×3.5mm,黑色到乌黑色,沥青光泽到半金属光泽,密度为8.87~9.12g/cm3,反射光下为灰白色。实验表明,有利于晶质铀矿生长的条件是:强还原场、温度>450℃、压力>120 MPa、强酸性(pH<4)、稀溶液(铀含量小于23.8mg/mL)。更多还原

【Abstract】 The experiment result of octagonal crystal uraninite was introduced and their mineralogy feature was studied in this paper.The shape of uraninite synthesized in the laboratory pressure vessel is with different size and combination shape.The most common combinations are tower,ribs,leaves and branches.The biggest synthetic cristal of unaninite is 2.5mm×3.5mm,which is black to jet-black in color and asphlt to semi-metallic in luster and 8.87 to 9.12g/cm3 in density.The favor sythetic condition for uraninite is:strong reducing field,above temperature 450℃,above 120 MPa,strong acid(pH <4),dilute solution(uranium content is less than 23.8mg/mL).更多还原
