Diamond & Quantum Weekly | Jul 13–19, 2026
Hubei Carbon Six signed a RMB200 million project in Xining, highlighting power and infrastructure as MPCVD location variables while remaining at the signing stage.
Weekly signal
Hubei Carbon Six and the Xining Dongchuan Industrial Park signed a diamond-semiconductor material project reported at RMB200 million. The stated direction included CVD diamond, optical windows, and chip-cooling products.
The location highlighted electricity price, renewable-energy access, supply stability, industrial space, and infrastructure as MPCVD manufacturing variables. Energy advantage matters only if it accompanies process control, utilization, yield, finishing, and customers.
The largest reported format—up to eight inches—was a company statement. Public reporting did not identify whether every product was single crystal or polycrystalline, nor disclose yield, output, specifications, or customer acceptance. The project was still at the signing stage.
Other candidate stories were downgraded because they repeated earlier disclosures or remained at sample-testing stage. A newly republished research article was not counted as a new weekly event.
The period’s lesson was to separate location economics and project intent from actual manufacturing evidence.
Evidence limits and uncertainties
- The reported maximum eight-inch format was a company statement; product type, yield, output, and customer acceptance were not disclosed.
