Summary
A line runs precursor from creels through oxidation ovens (ORNL: up to 400°C), low-temperature carbonization (to 1000°C) and high-temperature carbonization (to 2000°C). Harper International supplies ovens and furnaces; its 2018 contracts were about $90M. ORNL CFTF has a 390-ft flexible line and a microwave/plasma line in development.
