摘　　要：以钛铁矿为原料,通过等离子体化学气相沉积,生长纳米碳管.再通过微波加热强制碳化得到碳化钛-纳米碳管(TiC-CNTS)复合粉体.研究纳米碳管的生长工艺和微波碳化处理工艺,得出合理的制备工艺条件:纳米碳管的制备条件为微波功率600 W,腔体气压5.5 kPa,甲烷流量3.3 mL·min-1,氢气流量55 mL·min-1,生长时间40 min.碳化条件:微波功率700 W,处理时间10 min.Carbon nanotubes were first obtained by MPCVD by using ilmenite as raw material,and then they were compulsory carbonization by microwave heating to obtain carbon nanotubes-carbonization titanium composite（TiC-CNTS） powder.The growth and microwave carbonization process of carbon nanotubes were systematically studied to obtain perfect technique.The reasonable preparation conditions for carbon nanotubes was microwave power 600 W,chamber pressure 5.5 kPa,methane flux 3.3 cm3·min-1,hydrogen flux 55 cm3·min-1,and the deposition time was 20 minute.As for carbonization,the microwave power was 700 W and the carbonization time was 10 min.
