Method and reactor for manufacturing particles

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.
