Synthetic Hexagonal Diamond Summary - Development: Researchers have created a synthetic diamond with a hexagonal lattice structure, surpassing natural diamonds in hardness and stability. - Process: The diamond is produced by heating graphene under high-pressure conditions, addressing past issues of size and purity. - Advantages: It exceeds natural diamonds in pressure tolerance (beyond 70-100 GPa) and thermal stability (above 700°C). - Applications: Ideal for industrial uses such as drilling, machining, data storage, and thermal management; not suitable for jewelry due to its structure. - Future Focus: Efforts are ongoing to scale production for broader industrial applications.
