Abstract

A powdered heterogeneous substance is produced by treating a dispersion, suspension or emulsion in a turbulent or laminar burner under specified conditions, feeding the reaction mixture into a tube where it is further treated and then feeding it to a scrubber, separator or filter for further treatment.
