利用高分辨透射电子显微镜技术得到天然低温久辉铜矿的畴结构及缺位结构图像. 东乡久辉铜矿[100]高分辨晶格像显示: (1) 天然低温的久辉铜矿中存在久辉铜矿与蓝辉铜矿纳米级交生的畴结构. 虽然两者之间存在六方辉铜矿状结构过渡带, 但它们仍然遵循(100)久辉 //(111)蓝辉的结晶学取向关系; (2) 天然低温久辉铜矿中存在1.56%-3.12%的Cu原子缺位. 在久辉铜矿的单位晶胞中平均每b0/2的宽度就会存在1-2个Cu原子的缺位, 这一缺位率与其成分Cu1.93～1.97S相吻合. High-resolution transmission electron microscopy was used to obtain the domain structure and absence image of the natural low-temperature Jiuhui copper deposit. The high resolution lattice image of the Donghui Jiuhui copper deposit [100] shows that: (1) Although the hexagonal chalcocite transition zone exists between them, they still follow the crystal of (100) JIU Hui // (111) blue-hui (2) 1.56% -3.12% of Cu atoms are absent in the natural low-temperature Jiuhui copper deposit, and an average of every 1/2 of the width of b0 / 2 exists in the unit cell of Jiughui copper deposit The absence of Cu atoms coincides with the composition Cu1.93 ~ 1.97S.
