Lonsdaleite, often called hexagonal diamond, is an allotrope of carbon with a unique structure that theoretically makes it harder than diamond. Unlike diamond's cubic crystal structure, Lonsdaleite has a hexagonal arrangement, which could make its bonds stronger under certain conditions. Diamonds are f...
What I think we should get is that basic structure of Baird, but not as complete as his Lonsdaleite diamond. In other words, that cubic structure will be created, but it will contain a lot more air. More missing linkages. But can my theory explain NaCl7 as easily? Yes. All we have ...
Lonsdaleite – A material stronger and stiffer than diamond Based on first-principles calculations, we demonstrate that lonsdaleite exhibits many excellent static mechanical properties. For instance, the compressive... Q Li,S Yi,Z Li,... - 《Scripta Materialia》 被引量: 33发表: 2011年 ...
Lonsdaleite, also called hexagonal diamond, has been widely used as a marker of asteroidal impacts. It is thought to play a central role during the graphite-to-diamond transformation, and calculations suggest that it possesses mechanical properties superior to diamond. However, despite extensive ...
