Patent ID: 6837076

Claim:
A method of making oxide soot comprising the steps of: providing a burner comprising a first substantially planar layer having a first opening therethrough; a second substantially planar layer having a planar surface defining a burner face, the layer having a second opening therethrough and being bonded to the first layer such that the first and second openings are generally aligned to form an orifice in a central region of the burner; a plurality of gas openings having dimensions less than about 150 microns through the burner face for allowing a combustible gas and auxiliary gasses to exit the burner; gas channels in fluid communication with the gas openings; and precursor channels in fluid communication with the orifice; flowing the combustible gas and auxiliary gas through the gas channels and gas openings; igniting the combustible gas to provide a flame; flowing precursor through the precursor channels, through the orifice and into the flame to combust the precursor and form the oxide soot.
