Abstract

An experiment was designed to prepare isotropic pyrocarbon by thermal gradient chemical vapor deposition apparatus. The deposition was performed under ambient atmosphere at 1400 °C, with natural gas volume flow of 3.5 m ³/h for 80 h. The results show that the thickness and the bulk density of the deposit are about 1.95 g/cm³ and 10 mm, respectively. The microstructure of the deposit was examined by polarized light microscopy and scanning electron microscopy, which shows that the deposit is constituted of sphere isotropic pyrocarbon, pebble pyrocarbon and laminar pyrocarbon.
