摘要
With admixture of n-diamond and diamond-like carbon powders （DLC） as carbon source, transparent wafers have been synthesized by hydrothermal process at 100℃ and atmosphere pressure. Scanning electron microscopy, X-ray diffraction, Raman spectroscopy, transmission electron microscopy, electron-probe microanalysis and Fourier-transform infrared spectrometer were used to analyze those transparent wafers. These results indicated that the transparent wafers were amorphous sp^3-banding carbon wafer, and that the wafers were not aggregate of DLC from the carbon source but a new kind of reaction product by hydrothermal treatment.
