"placed into gas stream in non-oxidizing environment, possess high thermal conductivity, spreading heat evenly/ preventing hot spots... significantly more heating power per unit of mass than metal alloys... can be woven, knitted, tied into knots, creating high-surface-area 3D structures, lightweight so porous, maximizing contact with gas... heaters can be designed in complex shapes using textile manufacturing techniques, fitting into smaller/ uniquely shaped equipment... chemical production/ thermal treatment"
