ABSTRACT:
In a flame hydrolysis method for depositing glass soot used ultimately to make optical fiber, a reactant that forms the glassy soot stream is delivered to the torch (20) in liquid form and an ultrasonic nozzle (34) in the torch atomizes the reactant or breaks the reactant into a fine mist without the use of a gas.
