摘要： The invention is relates to CVI/CVD furnace apparatus. More specifically, the invention is directed to a sealed gas inlet for a high temperature CVI/CVD furnace. A method and apparatus are provided for preventing gas leakage around a gas inlet extending through a hole in a susceptor floor in a CVI/CVD furnace. According to the invention, the gas inlet is sealed to the susceptor floor with sufficient intimacy to block leakage of gas through the hole around the gas inlet while allowing the gas inlet to cyclically translate through the hole due to thermal expansion and contraction induced by thermal cycles in the CVI/CVD furnace.

摘要： The invention relates to a susceptor lid for use in a CVI/CVD furnace. More specifically, the invention is directed to a lid configured to consecutively run CVI/CVD and heat treatment processes without opening the furnace. The susceptor lid according to the invention comprises a susceptor lid body having a gas exhaust hole; and, an exhaust lid disposed over said gas exhaust hole, said exhaust lid being configured to move within the CVI/CVD furnace from a first position wherein said exhaust lid covers said gas exhaust hole to a second position wherein said gas exhaust lid at least partially uncovers said gas exhaust hole.
