在国产六面顶砧高压装置上，以Ni 70 Mn 25 Co 5合金为溶剂/催化剂，在5.5GPa和1500-1560 K的压力下，用温度梯度法生长了Ib型金刚石。用傅里叶变换红外光谱仪（FTIR）测定了不同合成温度下合成的Ib型金刚石中氮（CN）的含量。研究了金刚石中CN含量与合成温度的关系。对于以Ni 70 Mn 25 Co 5为催化剂合成的Ib型金刚石，其CN值沿着合成温度的升高而降低。
Type Ib diamonds were grown by the temperature gradient method (TGM) at 5.5 GPa and 1500–1560 K in a china-type cubic anvil high pressure apparatus using Ni70Mn25Co5alloy as solvent/catalyst. The concentration of nitrogen (CN) in type Ib diamonds synthesized at different synthesis temperatures was measured by a Fourier transform infrared (FTIR) spectrometer. The dependence ofCNin diamond on synthesis temperature was studied. For the type Ib diamonds synthesized using Ni70Mn25Co5as catalyst, itsCNdecreases along with the increase of synthesis temperature.
