A process for stabilizing precursor fibers for the production of carbon fibers is disclosed. The process comprises the following steps: continuously introducing, passing and removing said precursor fibers into, through and from a process chamber; establishing a predetermined process gas atmosphere different in composition from ambient air in said at least one process chamber, said process gas atmosphere containing at least one of a reactive component and a catalyst having a predetermined partial pressure; while said precursor fibers are in said process chamber, heating the precursor fibers to at least a first temperature and maintaining said first temperature for a predetermined period of time.
