ABSTRACT:
Apparatus for forming a vapor of material to be hydrolyzed and/or oxidized and entraining the vapor in a carrier gas. The source material, in liquid form, is pumped to a point in the column above a porous packing. As the liquid progresses downward through the packing, it encounters a rising countercurrent of carrier gas. The source material vaporizes and is delivered to vapor deposition by the carrier gas. The source material vaporized in the apparatus may alternatively be delivered to an externally heated tubular reactor, or to any other kind of chemical vapor deposition (CVD) reactor.
