以硼氢化钠和叠氮化钠为原料，在高压反应釜中于600°C反应制备了纳米氮化硼（BN）。X射线粉末衍射分析表明，产物为六方BN，晶胞常数为a= 2.495nm，c= 6.687nm。透射电子显微镜观察结果表明，该纳米粒子由平均尺寸为200 nm × 20 nm的晶须状颗粒组成。用FT-IR、XPS和TGA对产物进行了表征。它具有良好的热稳定性和高温抗氧化性。
Nanocrystalline boron nitride (BN) was synthesized via a simple route by the reaction of sodium borohydride with sodium azide in an autoclave at 600°C. X-ray powder diffraction pattern indicated that the product was hexagonal BN, and the cell constant was a=2.495Å, c=6.687Å. Transmission electron microscopy image showed that it consisted of whisker-like particles with an average size of 200nm×20nm. The product was also studied by FT-IR, XPS and TGA. It has good thermal stability and oxidation resistance in high temperature.
