摘要
Abstract
The experiment result of octagonal crystal uraninite was introduced and their mineralogy fea-ture 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 bran-ches .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 .12 g/cm3 in density .The favor sythetic condition for uraninite is :strong reducing field ,above temperature 450℃ ,above 120M Pa ,strong acid (pH < 4 ) ,( 23 .8 / ) .关键词
