Quite a few claims of diamond synthesis had been documented between 1879 and 1928; most of these makes an attempt had been rigorously analyzed however none had been confirmed. Within the 1940s, systematic analysis started in america, Sweden and the Soviet Union to develop diamonds utilizing CVD and HPHT processes. The primary reproducible synthesis was reported round 1953. These two processes nonetheless dominate the manufacturing of artificial diamond. A 3rd technique, referred to as detonation synthesis, entered the diamond market within the late 1990s. On this course of, nanometer-sized diamond grains are created in a detonation of carbon-containing explosives. A fourth technique, treating graphite with high-power ultrasound, has been demonstrated within the laboratory, however at present has no business utility.
