PURPOSE:Powders of glass material resulting from gas phase reaction are made into a suspension using a sprayed liquid and collected for drying, thus obtaining efficiently soot with large bulk density using miniaturized vessels and units. CONSTITUTION:While the liquid raw materials are carried from vessel 1 by bubbling argon gas, oxygen gas is mixed in tube 3 and the mixture is introduced through tube 3 to one of the inlets for oxyhydrogen flame burner 4. Hydrogen is sent to another inlet and the flame hydrolysis is effected by the flame 5 to form oxide soot 6. Liquid 9 is sprayed from sprayer 8 around vessel 7 into the vessel to collect the soot 6a in the bottom of the vessel without flyloss as a temporary dispesion 10. The dispersion 10 is made to flow down through tube 11 into vessel for drying 12, heated by heater 13 and gradually dried to accumulate soot. |
