Classification: CPC B  C | IPC B  C

Claim 8:
9. An apparatus for forming a plurality of encapsulated particles, comprising:
a coaxial feed wire, comprising:
a crystalline wire core; and
an amorphous shell surrounding the crystalline wire core;

a heating source at which a first wire end of the coaxial feed wire is positioned; and
a collector disposed below the heating source;
wherein heating of the first wire end at the heating source forms a molten pendant drop at the first wire end from which a plurality of encapsulated crystalline particles are emitted onto the collector;
a high voltage source to which a second wire end of the feed wire opposite the first wire end is connected;
wherein the high voltage source applies a voltage in a range of 0-100 kV across the crystalline wire core.
