Fabrication of NbCx-C Three-Dimentional Netted Fibers
NbCx-C三维网状纤维的制备

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 12-38 m, the circumferences are 0.22-2.2mm, the hole diameters are 70-701 m. The proccesing conditions for fabricatingNbC_x-C 3-D netted fibers, and relative morphology of NbC_x-C netted fibers were investigated indetail.
