摘要:
A silicon oxide removal apparatus for removing silicon oxide contained in an inert gas discharged from a silicon single crystal manufacturing apparatus, including at least: a contact means for bringing the inert gas discharged from the silicon single crystal manufacturing apparatus into contact with a strongly alkaline solution; and a neutralizing means for neutralizing an alkaline material contained in the inert gas brought into contact with the strongly alkaline solution. As a result, there is provided a silicon oxide removal apparatus and a facility for recycling an inert gas for use in a silicon single crystal manufacturing apparatus that can more effectively remove the silicon oxide contained in the inert gas discharged from the silicon single crystal manufacturing apparatus at low cost and enable recycle of the inert gas in which the silicon oxide has been effectively removed.
