Zusammenfassung:There is provided a process and apparatus for the production of finely-divided metal and metalloid oxides by flame hydrolysis of corresponding metal and metalloid halides whereby burner fouling is minimized and burner fabrication is facilitated by transpiration of a fuel gas or vapor along the boundaries of each halide-containing stream as it is discharged from the burner into a reaction zone.
