[China Superhard Materials Network News] On November 13, the third China (Zhengzhou) International Abrasives Grinding Exhibition was grandly opened at the Zhengzhou International Convention and Exhibition Center. At 11:00 am, Antai Technology Co., Ltd. held a press conference in the exhibition hall and delivered a speech entitled “Detection of Impurity Elements in Synthetic Diamondsâ€, which attracted the participation of many industry participants.
The main contents of this conference are: introduction of the necessity of analysis of impurity elements in synthetic diamond, TI, TTI, magnetic, transmittance, etc., which can indirectly evaluate the quality of diamond; [O], [N], [other impurities The content of the diamond can directly hit the core of the diamond quality; more importantly, it also indicates the direction of improving the quality of the diamond, reducing the [O] and [other impurities] content. This report describes the use of oxygen and nitrogen analyzers, inductively coupled plasma optical emission spectrometer (ICP-AES) to test the oxygen and nitrogen content and impurity content of synthetic diamond, using nickel bath bath and wet ink capsule method to detect oxygen and nitrogen content, Using the method of high temperature burning ashing and acid dissolution, selecting the sensitive line without interference as the analysis line and using the optimized analysis conditions, the analytical method for determining the ten impurity elements in synthetic diamond by ICP-AES method was established. The method solves the problem that the artificial diamond sample is not affected by the action of acid and alkali, and the impurity content can not be determined by the ICP-AES method, and satisfactory analysis results are obtained. Determination of the content of impurity elements in synthetic diamond hits the core of diamond quality, indicating the direction of improving diamond quality.
