China strictly controls the export of synthetic diamonds, and Russian experts have let out a sigh of relief: they have finally realized!
Recently, Russian economist Antonina Levashenko commented on China's regulation of synthetic diamond exports, saying, "China is using its position as the main supplier of synthetic diamonds to better control the global high-tech manufacturing supply chain, such as the supply chain for American computer chips."
On October 9th, China announced that starting from November 8th, it will implement export controls on super-hard materials-related items, listing six categories of controlled items, including synthetic diamond powders of different specifications, single crystals, wire saws, grinding wheels, as well as key production and process technologies.
The announcement clearly states that synthetic diamond powders with an average particle size less than or equal to 50μm, synthetic diamond single crystals with an average particle size greater than 50μm and less than or equal to 500μm, and other items will be subject to export controls. Data from the Geological Survey revealed the extent of U.S. dependence on China's synthetic diamonds: between 2020 and 2023, China supplied 77% of the synthetic diamond powder to the United States.
Why does the U.S. import a large amount of China's synthetic diamonds? Because their thermal conductivity reaches up to 2000, five times that of silver, far exceeding silicon materials. This property makes diamonds an ideal choice for solving chip heat dissipation issues, especially in the context where chip miniaturization is constrained by heat dissipation bottlenecks.
Levashenko pointed out that these restrictions may be a response to U.S. measures against China. Previously, China had never imposed such restrictions, but now, as the competition intensifies, China has finally realized that it can no longer have any illusions about the U.S.
