1. A method for manufacturing particles comprising the steps:
(a) bringing at least one starting material into a reactor;
(b) subjecting the at least one starting material to a thermal treatment of a pulsating process gas stream in a treatment zone of the reactor;
(c) forming particles; and
(d) bringing the particles which are obtained in steps (b) and (c) out of the reactor,
wherein the temperature regulation of the process gas stream is decoupled from the generation and maintenance of the pulsation of the process gas stream,
wherein the at least one starting material is thermally treated in the treatment zone at a treatment temperature of 100° C. to 3000° C. and a retention time in the range of 0.1 s to 25 s,
and
wherein the pulsation is confined to a process space by at least an installation part which is designed as a flow necking or as a throttle arranged upstream and/or downstream of the process space and adjacent thereto.
