Abstract: By the carbothermal method and different additives, NbC_x(x=0.98)--C three-dimensional netted fibers were prepared in graphite resistance furnace with 0.1 MPa/N₂ ambient atmosphere attemperatures of 1070 to 1670℃. The diameters of 3-D netted fibers are 12-38μm, the circumferences are 0.22-2.2mm, the hole diameters are 70-701μm. The proccesing conditions for fabricating NbC_x-C 3-D netted fibers, and relative morphology of NbC_x-C netted fibers were investigated indetail.

Key words: carbothermal method, NbC_x-C netted fibers, processing condition, the morphology
