Abstract 1. A METHOD FOR CONTINUOUSLY DEPOSITING NODE-FREE AMORPHOUR BORON TO UNIFORM THICKNESSES GREATER THAN 0.6 MIL ON A MOVING RESISTIVELY HEATED CARBON WIRE AS IT IS DRAWN THROUGH A SERIES OF REACTORS COMPRISING THE STEPS OF: MAINTAINING THE CARBON WIRE IN THE FIRST REACTOR AT A TEMPERATURE OF 1600*-2100*C.; EXPOSING THE CARBON WIRE WHILE AT SAID TEMPERATURE IN AT LEAST ONE REACTOR TO A GASEOUS STREAM CONSISTING ESSENTIALLY OF A CARBON-CONTAINING GAS ADMIXED WITH A DILUENT GAS TO EFFECT DEPOSITION OF PYROLYTIC GRAPHITE ON THE CARBON WIRE; MAINTAINING THE GRAPHITE-COATED CARBON WIRE IN A SUBSEQUENT REACTOR AT A TEMPERATURE OF 700*-1400*C., AND EXPOSING THE WIRE IN SAID SUBSEQUENT REACTOR TO A GASEOUS STREAM OF A BORON HALIDE ADMIXED WITH HYDROGEN TO EFFECT DEPOSITION OF ELEMENTAL BORON THEREON; SAID DEPOSIT OF PYROLYTIC GRAPHITE BEING DISPOSED TO PREVENT FRACTURE OF THE CARBON WIRE BY THE BORON.
