一种纳米氮化硼管的制备方法
摘要：
一种纳米氮化硼管的制备方法，其特征在于：以TiB2、TaB2、MoB、Mo2B5金属硼化物为催化剂和硼源，以氮气为稀释气，在高温下气相生长生成BN管，生长温度区间为1100℃—1400℃，生长时间1—2小时，NH4Cl与N2的摩尔比为1∶5—1∶12。本发明可以生成比电弧法和激光烧蚀法纯度高和质量高的BN管。
摘要（英）：

A process for preparing nm-class BN tubes features that such metallic borides as TiB2, TaB2, MoB, or Mo2B5 are used as catalyst and B source, nitrogen gas is used as diluting gas, and the BN tubes are grown at 1100-1400 deg.C for 1-2 hr in high-temp. gas phase. The mol ratio of NH4Cl to N2 is 1 : 5 through 1 : 12. Obtained BN tube features high purity and high quality.
