**New, lower temperature way found to make diamonds"**
01:21 PM ET 07/09/98 Release at 4 p.m. EDT WASHINGTON (Reuters) - Chinese scientists Thursday reported finding a new way to make diamonds, heating carbon and sodium at temperatures lower than previously used. They said their method was not perfect but a step to devising better ways to make diamond, which is widely used in industry. The researchers from Structure Research Laboratory and Department of Chemistry at the University of Science and Technology in Hefei, China, used a process called metallic reduction-pyrolysis-catalysis (RPC). "This method is a simple means of forming diamond,'' they wrote in a report published in the journal Science. The RPC process produced diamond powder at a yield of about 2 percent and graphite -- which, like diamond, is pure carbon but in the form of a grayish powder rather than the very hard crystal that is a diamond. Sodium, a nickel-cobalt alloy and carbon tetrachloride were put into a stainless steel container and heated at 1,290 degrees Fahrenheit for 48 hours, then removed to cool to room temperature. "This temperature is much lower than that of traditional methods,'' they wrote. Their tiny, grayish-black diamonds are a far cry from the most valuable industrial diamonds. "Improvements in the process of synthesizing of diamonds are still needed,'' they wrote. Diamonds have been synthesized previously at 1,470 degrees Fahrenheit), using carbon, water and metal. Synthetic diamonds differ in size, shape and impurities from natural diamonds. They also can be formed with the use of explosives. The researchers ran their gray-black powder through a X-ray diffractometer, a transmission electron microscopy and a Raman spectrum to confirm the formation of diamonds. They said finding a catalyst better than sodium may help in the process of making diamonds. ^REUTERS@
