摘要：
A method and apparatus for producing metastable nanostructured materials employing a ceramic shroud surrounding a plasma flame having a steady state reaction zone into which an aerosol or liquid jet of solution precursor or powder material is fed, causing the material to be pyrolyzed, melted, or vaporized, followed by quenching to form a metastable nanosized powder that has an amorphous (short-range ordered), or metastable microsized powder that has a crystalline (long-range ordered) structure, respectively.
