The effect of adding Cu on the nitrogen removal efficiency of Ti for the synthesis of a large type IIa diamond under high temperature and high pressure

Synthesis and Characterization of Fe–C–Si System Ib-Type Gem-Grade Diamond Single Crystals under High Temperature and Pressure

“…Diamond, being one of the most unique natural materials, finds wide applications in various fields such as jewelry, mechanical processing, semiconductors, and electronic communication. − The high-temperature and high-pressure method is a successful technique to mimic the growth environment of natural diamonds. In 1971, researchers synthesized the first large diamond by employing a temperature gradient method utilizing graphite and metal catalysts under conditions of elevated temperature and pressure.…”
