HPHT (High Pressure High Temperature) synthesis cycles last for several hundred hours. Any millisecond-level voltage drop or power grid fluctuation can instantly disturb the thermal-pressure field, causing growth lines, internal stress, or inclusions. The ultimate consequence at the cutting stage is stone breakage and low yield—an industry-wide pain point that is difficult to solve. At […]

In HPHT synthetic diamond production, humidity is not the most critical technical variable — but it is a stability factor that has long been underestimated. Synthetic pyrophyllite assembly components are moderately hygroscopic. When moisture content is elevated, water vaporizes and expands under high-temperature, high-pressure conditions, potentially causing: In southern regions, where ambient humidity remains high
