Abstract
Diamond particles prepared by chemical vapour deposition from a mixture of methane and hydrogen gases have been examined by electron microscopy. The particles were crystalline with a cubic structure. The typical habit was cubo-octahedron and twinned crystals, i.e. spinel-law twins and multiply-twinned particles, were also observed. Four cage compounds, i.e. bicyclo[2.2.2] octane, tetracyclo[4.4.0.13,9.14,8] dodecane, hexacyclo[5.5.1.12,6.18,12.03,11.05,9]pentadecaneand dodecahedrane are proposed for embryos of twinned crystals.
