| 摘 要： | 用X射线衍射法，对不同结晶度的石墨型氮化硼（gBN）在冲击波作用下转变成的纤锌矿型氮化硼（wBN）产物进行了研究，对wBN中的杂质含量等进行了分析。结果表明：gBN的石墨化指数G.I值对wBN的产率有明显的影响。 |

| Abstract: | X-ray diffraction observations were used to analyze the phase transformation of graphite-type BN (gBN) with different crystallinities to wurtzite-type BN (wBN) under the same shock compression conditions. Impurities contained in the wBN powders were also estimated. Results show that the coversion ratio from gBN to wBN are greatly affected by the graphite index number (G. I) of the raw materials. |
| Keywords: | X-ray diffraction phase transformation crystallinity. |
