Understanding the HPHT Process
The HPHT process simulates the natural conditions under which diamonds form in the Earth’s mantle. By applying extreme heat and pressure, a small diamond seed is placed in a growth cell filled with carbon and a catalyst. The temperature can exceed 1,300 degrees Celsius, while the pressure is elevated to over 50,000 atmospheres. This environment allows the carbon to crystallize around the seed, forming a synthetic diamond.
Growth Cells and Their Importance
At the heart of every HPHT diamond machine is the growth cell. This chamber contains the diamond seed, carbon source, and catalyst required for diamond formation. The design and materials of the growth cell significantly influence the quality and size of the diamonds produced. Manufacturers like Huanghe Whirlwind and Labrilliante have optimized these cells for better performance and durability.
