AB - A process for producing ultrafine silica particles incorporating a plasma transferred‐arc reactor of novel design (Plas‐macan) was developed. The process consisted of vapourizing small particles of sand (99.5% SiO2) which subsequently dissociated into SiO gas and oxygen in the presence of an argon plasma. Quenching of this gaseous mixture reconstituted SiO2 in the form of an aerosol. Various reacting media (H2, steam or NH3) were tested to assist the dissociation and to enhance the properties of the particles produced. The quenching of the particles was effected with oxygen or steam. A feedrate of 1.3 kg/h SiO2 and a power of 30 kW for plasma generation were used throughout the work. Amorphous silica particles, average 0.07 μm in diameter, were produced.
