beyond again esearchers at the Carnegie Institutions Geophysical Laboratory cause learned to discover 10-carat, half-inch thick single-crystal diamonds at rapid offset printing rates (100 micrometers per hour) using a chemical vapor bank deposit (CVD) process. This size is approximately five times that of commercially obtainable diamonds produced by the standard high-pressure/high-temperature (HPHT) method and other CVD techniques. In addition, the team has made colorless single-crystal diamonds, transparent from the ultraviolet to unseeable light wavelengths with their CVD process.
"High-qua lity crystals over 3 carats are very operose to produce using the conventional approach," commented Dr. Russell Hemley who leads the diamond effort at Carnegie. "several(prenominal) groups have begun to grow diamond single crystals by CVD, stingy large, colorless, and flawless ones remain a challenge. Our fabrication of 10-carat, half-inch, CVD diamonds is a major(ip) breakthrough." The results were reported...If you pauperization to get a full essay, order it on our website:
