【摘要】 本文从结晶化学角度研究了Ｌｉ２Ｂ４Ｏ７晶体结构，根据晶体的结构基元为［Ｂ４Ｏ９］６－络阴离子，并用计算机绘出了该络阴离子在｛００１｝，｛１００｝，｛１１０｝面上的投影，由［Ｂ４Ｏ９］６－络阴离子的结晶方位和分布确定了晶体的开裂是沿着络阴离子之间相连接的桥氧部位所断裂的．更多还原

【Abstract】 In this paper the lithium tetraborate crystal structure was studied from crystallography. The basicstructural unit was a [B4O9]6- anion. The [B4O9]6- anions projection on {001}, {100}, {110} wasdrawn., Based on the crystalline orientation and distribution of [B4O9]6- anions, the crystal cracks alongthe bridge-oxygen interlink place of the anions.更多还原
