METHOD OF FORMING MIXTURE OF COMPOUND |
摘要 |
<p>A process is disclosed for the formation of a uniform and homogeneous mixture of a plurality of compounds in a desired stoichiometric ratio as a precipitate from a fluid under supercritical processing conditions which comprises dissolving at a first supercritical temperature a stoichiometric mixture of compounds in a fluid in a closed reaction vessel having a fixed first volume and rapidly expanding the volume in which the fluid is confined to lower the density sufficiently to cause the stoichiometric mixture of compounds to precipitate as a unifrom and stoichiometrically accurate mixture of the compounds, preferably without changing the phase of the fluid. The process may be used to form a high quality superconductor material because of the uniform and homogeneous distribution of the precipitated components in a stoichiometrically accurate ratio throughout said mixture.</p> |
