中文摘要：

以氟硼酸盐和氨基钠为反应原料,氨基钠或金属钠为生长介质,在600℃下恒温反应24h,成功制备出了三角形和六边形片状氮化硼微晶。XRD、FT-IR和XPS分析表明,产物为六方氮化硼,无其它物相存在。FESEM和TEM分析发现在氨基钠熔体中产物为三角形片晶,而在氨基钠和钠混合熔体中得到的是六边形的氮化硼片晶。三角形片晶边长约400～500nm,厚度约为100nm;六边形片晶的边长在300～500nm范围内,厚度约100～150nm。研究结果表明,NaNH2不仅能作为氮源,同时也是氮化硼晶体生长的介质。

英文摘要：

Triangles and hexagons BN were prepared by using NaBF4 and Na as raw material, NaNH2 or Na as the growth medium at 600℃ for 24 h. The identification of BN was studied by using XRD, FT-IR and XPS. The morphology of phases were characterized with FESEM and TEM. The results showed that triangles BN and hexagons BN can be obtained in the growth medium of NaNH2 and in the presence of NaNH2 and Na re- spectively. The triangles BN has a length about 400-500nm and 100nm in height while the hexagons BN has a length at 300-500nm and 100-150nm in height. The results indicated that NaNH2 not only act as the nitrogen source but also can be used as the growth medium of BN.
