| titleOfInvention | Method for producing pyrogenic silica |
| abstract | The problem solved by the present invention is to develop an economical method for producing pyrogenic silica, in which the silicon compound having a low ignition temperature does not cause combustion in the mixing chamber of the burner before entering the burner nozzle. and can be used as a starting material. In addition, the described problem of the formation of highly flammable or exothermic coatings is minimized. This problem is solved by the provision of a process for the production of pyrogenic silica, wherein the mass flow a containing one or more combustion gases is dichlorosilane (H 2 SiCl 2 ), monochlorosilane (H 3 SiCl) or combined with a mass flow b containing at least one silane selected from the group consisting of monosilane (SiH 4 ) or mixtures thereof without the use of a static or dynamic mixing element to form a mass flow c; mass stream c is fed to mass stream d containing at least one oxygen source; mass flow c and mass flow d are mixed using a mixing element to form mass flow e; The mass flow e is introduced into the reaction chamber, ignited and reacted; The resulting solids are separated out. The invention also provides an apparatus for carrying out such a method. The process according to the invention makes it possible to produce pyrogenic silica from silicon compounds having a low ignition temperature, without premature ignition taking place before these starting materials enter the burner nozzle. The formation of highly flammable or exothermic coatings is minimized. The device according to the invention allows this method to be performed optimally. |
