Abstract
A method is provided for making substantially transparent polycrystalline diamond film having a thickness greater than 50 microns which can be used in glazing applications and as a heat sink in microelectric applications. A mixture of hydrogen and methane is conveyed into a heated filament reacting zone which is adjacent to an appropriate substrate, such as a molybdenum substrate to produce non-adherent polycrystalline substantially transparent diamond film.
