Boron and boron carbide by vapor deposition
Electrodeposition and Surface Treatment, 1974 Abstract Boron trichloride can be reduced by hydrogen at 1,300°C with a recovery of approximately 85% as elemental boron. The optimum H2 to BCl3 molar ratio was 30 under the test conditions used. No reaction between tungsten substrates and the boron deposits could be detected.
