Schematic of the enclosed FSP setup with a particle formation zone (1), an ACB-coating (2), and a quenching (3) zone. By enclosing the unit with quartz tubes, the O2 stoichiometry in the ACB-coating zone can be controlled precisely. The coated particles are cooled with N2 at the end of the coating zone to avoid carbon black combustion after contacting ambient air on the way to filtration.
