Abstract
PURPOSE: To efficiently obtain a boron sheet by forming prescribed substance layers on graphite, chemically vapor-depositing boron on the resulting substrate, and removing the substrate.
CONSTITUTION: A chromium or chromium boride layer is formed on graphite, and on the layer a titanium or titanium boride layer is formed to obtain a substrate. Boron is then deposited on the substrate by a chemical vapor deposition method, and the substrate is removed to obtain a boron sheet. The preferred thickness of the chromium or chromium boride layer is 0.5W10μm, and that of the titanium or titanium boride layer is 0.2W15μm.
