    摘要: A gaseous reactant supply apparatus for turning high flow rates of gaseous supply approximately 90 degrees and providing a uniform distribution of gaseous supply. The gaseous supply passes through a venturi throat. Straightening vanes can be positioned inside the venturi throat to reduce rotational motion the gaseous reactant supply may have upon entering the venturi throat. The gaseous reactant supply apparatus exhibits lower pressure drops than exhibited by apparatus of the prior art.

    摘要: Process for the production of a finely divided oxide of a metal or silicon by the hydrolytic conversion of a volatile corresponding metal halide or silicon halide in a flame, said process comprising feeding the volatile halide in a mixture with a combustible hydrogen-containing gas and air or oxygen to a burner provided with a mouth emitting a flame, burning the mixture in a fire tube to form a first portion of water vapor, said burner surrounded by an annular chamber forming a nozzle through which hydrogen is passed to keep the mouth of the burner free of attachments of solid substances, the quantity of oxygen or air being sufficient for the practically complete combustion of the combustible gas, and the quantities of oxygen or air and combustible gas being sufficient to produce the first portion of water vapor which will at least suffice for the hydrolysis of the volatile halides, and further wherein said flame is allowed to burn in an atmosphere consisting of gases containing a second portion of water vapor, to avoid the formation of halogen gas in waste gases and separating the resulting oxide from other reaction products. The finely divided oxides are useful as additives and fillers in the manufacture of coatings, adhesives and elastomers.
