What is Hexagonal Diamond?

Hexagonal diamond, or lonsdaleite, is a form of diamond with a hexagonal crystal structure, unlike the cubic lattice of conventional diamonds. Discovered initially in meteorites, this material has recently been synthesized in larger quantities, showcasing its potential as a game-changer in advanced industrial applications.

Key Properties of Hexagonal Diamond:

Extreme Hardness: Hexagonal diamonds exhibit a hardness of approximately 155 Giga Pascals (GPa), surpassing the 100 GPa of natural diamonds.

Thermal Stability: They maintain structural integrity at temperatures up to 1,100°C, significantly outperforming natural diamonds that remain stable up to about 700°C.

Crystal Structure: The hexagonal arrangement of carbon atoms contributes to its enhanced strength and durability.

Innovative Synthesis Process

The synthesis of hexagonal diamond involves heating highly compressed graphite under precise conditions. By carefully manipulating pressure and temperature, researchers have managed to produce millimeter-sized, highly oriented blocks of stacked single-crystal-like nanolayers. This innovative approach allows for the creation of larger and purer samples than previous methods, paving the way for potential industrial-scale production.
