beyond again esearchers at the Carnegie Institutions Geophysical Laboratory draw learned to discover 10-carat, half-inch thick single-crystal diamonds at rapid cognitive process rates (100 micrometers per hour) using a chemical vapor bank deposit (CVD) process. This size is approximately five times that of commercially gettable 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 infrared frequency light wavelengths with their CVD process.
" ;High-quality crystals over 3 carats are very catchy 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, scarce 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 emergency to get a full essay, order it on our website:
