Abstract
Abstract Chemical reactions are carried out under the thermal action of the plasma of an arc discharge by causing a reactant containing a metal or metalloid to swirl and form a vortex in the liquid state so as to at least partially form and stabilize a plasma, and said reactant reacts in the plasma state to form a reaction product containing at least one metal or metalloid component. Chemical reactions which may be carried out are for example reduction, cracking reactions, decomposition and recombination reactions, oxidation, carbide formation and nitride formation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
84 words
A process as set forth in claim 1, in which said another reactant is also caused in its liquid state to swirl and form a further vortex around the arc discharge path, stabilizing another section of the arc discharge with said further vortex, and evaporating the said another reactant at the inside of said further vortex and forming a further part of the plasma of the arc discharge therewith, whereby said one and said another reactants react with each other in the plasma state.
Claim 2
Dependent Claim
32 words
A process as set forth in claim 1, including forming the plasma of the arc discharge only by said at least one swirled and evaporated reactant without introduction of supplemental inert gas.
Claim 3
Dependent Claim
28 words
A process as set forth in claim 1, wherein said another reactant is mixed with said one reactant and swirled together to form said at least one vortex.
Claim 4
Dependent Claim
39 words
A process as set forth in claim 1, including establishing a plurality of vortices of different reactants in succession along and around the arc discharge path, and withdrawing different reaction products at points spaced along the arc discharge path.
