Скачать или смотреть How China just built a synthetic superdiamond. And why nobody else can.

Chinese researchers have synthesized a nearly pure "superdiamond". It is of a revolutionary shape--hexagonal--with immediate applications in high-end machining, cutting, and polishing.

But this diamond was made of graphite, instead of carbon. Natural diamonds of similar hardness come from carbon, and are located in impact craters, making them very rare and small. This Chinese discovery will allow these super-hard "superdiamonds" to be built in labs, with graphite.

China and its BRICS trading partners have near-monopolies on the supply of graphite, and China itself refines nearly all of the graphite globally. And China has placed new export restrictions on graphite, choking off much of the supply to Western markets.
