摘要
Abstract
The shape, size and characteristics of inclusions in synthetic diamonds were revealed. The composition and mass fraction of the inclusions was analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES) , while mass fractions of the oxygen and nitrogen in diamond were analyzed by oxygen-nitrogen analyzer. It is specified that in China-made diamond mass fraction of inclusion decreased by an order of magnitude in the last decade, which is 0. 015% ~0. 037% , as compared to 0. 01% , the foreign high-grade diamond mass fraction of inclusion. The thermal toughness index ( TTI) of diamonds were also tested. The results indicated that TTI was significantly related to mass fraction of inclusion and oxygen. The TTI value of China-made diamond is closely similar to that of the foreign high-grade diamond. With the inherent defects of the diamond as a criterion, China diamond industry has already achieved a qualitative leap, even though it still lags behind the advanced foreign level. The improvement direction was stated in the end.关键词
