Large-Size Nanopolycrystalline Diamond (NPD)
www.diasemi.us
DIASEMI advances large-size nanopolycrystalline diamond (NPD) through a novel non-spontaneous nucleation synthesis route, integrating material design, high-pressure equipment, and synthesis-process engineering into a complete technology platform.
NPD is a strategic ultra-hard material with significant potential for ultra-precision machining, high-pressure science, and deep-earth/deep-sea drilling. By establishing new theories for microstructural design and control, this technology enables the synthesis of large-size NPD with highly engineered nanograin structures and exceptional mechanical performance.
